Spriggan (ONA)

I've watched this anime without seeing the original version, I don't think it's too bad to watch.
Therefore I have several conclusions about this anime.

The character designs are inconsistent in my opinion, sometimes from certain angles the characters' faces look strange, I know this is an old school anime, whether on purpose or not.

The storyline which in my opinion has no final goal, Each episode is just filled with protecting items from ancient times.
Especially for the last episode, it's really unclear, it just ends like that, this makes me disappointed.

It's a shame that this anime only has six episodes, this is another shortcoming in story telling. ... for example, MC's life at schools, only shows a few parts, even though I quite expected more from this school life.

Less like that, I don't really know why this anime ended with a low score, even though I don't think it's that bad.

I am writing this review from the perspective of someone who loved the manga and found the anime did not do it justice. You will already find plenty of reviews about this anime just as an anime or as an overall storyline concept. I was pretty excited to see this manga get an adaptation - I should not have been.

A huge part of what makes the Spriggan manga great is the art. So many of the interesting mythical creatures and areas are intricately drawn and wonderful to observe. It gives the world a huge amount of depth and feeling without having to say it ... using words. This goes double for major event reveals or monsters which have a style unto them which greatly enhances the story. The story was never going to be anything insanely complex or heartfelt, but it was a vehicle to get you to these interesting places and see wonderful art/interesting mythology and have a fun action fight mixed in.

The CGI elements and their heavy-handed use ensured none of this charm carried over. This leaves the story to fend for itself on the aspects of storyline and character development - characteristically where the Spriggan manga is weak. Another area the story telling in the anime format fails at is humor. The Spriggan manga is often more humorous, taking itself less seriously and having a lot more humor built in whereas the anime tries to make itself "cool" and a bit more serious. That just cannot work when you over the topics the way Spriggan does - which is silly let's be honest.

Without the wonderful art and beautifully detailed world nor the humor, the Spriggan anime is a shell of its manga self. I highly suggest anyone who did not like this anime or is potentially interested in it give the manga a shot instead.

There have been a few modern adaptations of old manga that were successful even in our modern era like Dororo, Ping Pong and Parasyte. Following this trend, Netflix made Spriggan (though they did Devilman Crybaby too) that was animated by 'David Production' (studio behind JoJos & Fire Force) and after that teaser and trailer I was quite hyped (like many) to see this action-packed old-civilization story but it had... a lot of problems.
This anime is pretty much the same as a certain full CGI Anime that aired last year; "Night Head 2041" which is also a spin-off for the manga "Night Head". They both are ... pretty terrible in many ways with only one selling point. For Night Head 2041, it's the Backgrounds and for Spriggan, its the decent fights (Yes. Not even good, just decent). Though one main difference is that Spriggan is an episodic story while Night Head had an overarching plot (a terrible one).

Each episode of Spriggan is different and follows "Yuu Ominae", a Spriggan equipped with "Armored Muscle Suit", a high-tech body armor/enhancer working under a organization called ARCAM, whose aim is to find out all the old civilization technology before baddies use it for...you know, world destruction/domination.
One of the main problems with Spriggan is that, it's old school in a very terrible way. Badass 16-year old protagonist with a lot of plot armor (no Pun intended)? Check.
A high-level secret society com organization plot? Check.
Bland villains with non-existent/stupid motives? Check.
Characters with very less relevance? Check.
Unsurprising/straight-up stupid reveals? Check.
Maybe Netflix believed in the "Old is Gold" motto a bit too much, because this Anime is pretty terrible. I'm not saying all these "modern adaptations of old manga" are terrible.
Crybaby, even though I don't like it that much is actually one of the most successful Anime on Netflix; Dororo which is like 50 year old still has some of the most emotional & dark moments; Parasyte falls into the same category and you should know about Ping Pong's legendary status even if you haven't watched it, then why is that Spriggan failed while others succeeded? Because Spriggan is;
1. Outdated: With HS romcoms, isekais and hyped battle shounens taking the spotlight, stories like Spriggan lost their charm. Many are willing to watch trashy power fantasies, self-insertable isekais, high-school romcoms or the next hyped battle shounens than treasure-hunt stories which became very outdated. (Cries in Golden Kauny)
2. Horrible story/characters: I haven't read the manga but I'm definitely not willing to read it because this show is that terrible, like just watch episode 1 and see how the 'reveal' works. I can't say how bad it is without using words like bad/terrible/horrible like a 20 times (though I probably did). Not to mention the story is actually incomplete, we still don't know what those red eyes the MC have or his 'dark' past, but I don't even care at this point. The scale is ridiculously huge too; one episode sets in America, the next in Germany, India, Russia and we aren't even talking about the amount of historical/religious references it makes. If it was atleast a bit well-written or atleast had decent characters, it actually would've been an decent ride. But it couldn't. It gets so bad that I couldn't even enjoy the fights anymore.
(Review for this Anime ends here. Skip to the last part for conclusion. But if you wanna see me talk about "old manga with new adaptations" I like...)

Some Anime like I mentioned above were able to entertain modern viewers despite the source material being old because they were pretty relevant. Crybaby took a storm on the community with those rap songs, uncensored angsty gore/nudity and that soundtrack, all of these elements made it look like a true modern anime and not just as "adaptation of an old manga". But the main thing that made them good is because they also had a solid story or good writing. Even though the gore put off in Crybaby, some of the drama in it is pretty amazing and it's ending actually made me like it when I initially hated it. Dororo & Parasyte, even though they took somewhat of a boring route they're still compelling shows due to either their plot or characters (they also had good soundtracks).

Spriggan is a terrible anime that had no reason to get a modern adaptation. If it wasn't for that decent CGI fights (& above average CGI) I probably wouldn't even watch this.
Have your friends by your side and make jokes when anything stupid; you might enjoy this more that way.
