JoJo no Kimyou na Bouken

Style - If there's one thing JJBA has in abundance, it's style. The art and animation in this OVA is absolutely wonderful. The character design is very stylish (I don't mind the fact that everyone looks like a bodybuilder), and the animation is fluid. The fight scenes are awesome. 3 out of 3.

Character - The characters have some recognizable personality but are not fully fleshed out. Jotaro is a bit of a thug - he broke D'Arby's finger for attempting to cheat at poker. Polnareff is a manchild, he is arrogant and constantly gets into fights for no good reason. That's about all that ... can be surmised from the little amount of character building that happens in this short OVA. There are practically no scenes devoted to character development, so we really don't get to know the characters in depth. Actually most of the character development happened in the 7-episode prequel OVA. The Joestars want to save Holly and the other team members are there to get revenge on Dio. So the overall picture is there, but the characters aren't quite fully fleshed out. Overall 2 out of 4 for having undeveloped yet sound characters.

Story - The story is pretty much nonsensical. Stands are somehow related to Tarot cards? This is never explained or explored. The villains are extremely inefficient at trying to kill the protagonists (I suppose if they were efficient, then the protagonists would never succeed) for example Hol Horse confronting Polnareff in the middle of the street and telling him about how his gun stand is superior to Polnareff's sword stand. Dio Brando being terrible at using his stand. Vanilla Ice acting like a complete idiot to get hit by Iggy and killed by Polnareff who was lying on the ground right in front of him. Jotaro suddenly developing the time-stop ability OUT OF NOWHERE just to defeat Dio. Polnareff jumping in to save Jotaro just as Dio is about to decapitate Jotaro. Dio landing exactly on Joseph's body after getting furiously punched by Jotaro. The entire stand thing makes no sense and the whole story is based around stands. It is truly bizarre. 0 out of 3 for not making any sense.

Oh and also, I might add that chocolate EXPANDS when molten, so the whole idea of D'Arby melting chocolate to make more room for an extra coin to be dropped into the cup makes no sense at all.

Overall 5 out of 10 for having undeveloped characters and a completely nonsensical story.

While I didn't go in expecting it to be pitch-perfect, I still found this to be a pretty mediocre adaptation of a fantastic manga, mostly let down by its brevity and tone compared to the original. Of course, given that there's a limit to just how much material CAN be included in 6 episodes without sacrificing the pace, it's not really a mistake so much as it is just a shame that so many fights, lines and moments were cut.
What stuck out most noticeably for me was that most of the comedy from the original was cut or toned down significantly; that may not ... seem like a huge drawback in and of itself, but comedy/comic relief forms a huge part of JJBA's charm and overall tone, so for it to be so played down was disarming.
Art-wise, I did enjoy the designs and some of the animation (there was some great animation on Polnareff particularly in the first two episodes) and generally speaking I did enjoy the 90s-ness of it all, both in terms of art and soundtrack (the opening sequence was probably my favourite part of the whole thing, honestly). I certainly found the art and colours in this more appealing compared to the muted, dingy palette of the 2000 episodes.
Overall, certainly *watchable* enough, but lacking in terms of charm, substance AND style compared to the source material- I can only hope that the new adaptation coming this year will be a little more faithful and upbeat (and from the looks of the Part I/II adaptation, it will be!).

In a nutshell, it is a story about formidable looking guys fighting each other using some sort of "spirits" called "Stand". The anime is quite brutal, there's blood and on screen dismemberment. The anime has unique visual style which I haven't really seen often.

Detailed breakdown below:

Story:
The OVA starts at the middle of the story, without explanation. Apparently it is based on one of the manga arcs, and OVA doesn't really explain what happened before. This may result in a fairly confusing experience. The story is linear series of encounters/battles with protagonist going towards certain goal. The encounters are dramatic and bloody. Basically it feels like ... "anyone can die" anime, which is good. If anything it sorta reminded me of Clamp X and of that one scene from Battle Angel Alita. The anime gets more interesting towards the end, where it finally moves to more interesting locations. Another thing is that fights are very imaginative. Powers of enemy users can control strangest things, and the combat encounters are quite tense.

Art:
The colors are washed out, and a lot of the anime happens in the desert with not much to see. The style is, however, unique (with formidable looking characters), and closer to the end there are locations with much more details and more people in it. In those ares there's incredible amount of details to surrounding, bystanders, etc.

Sound:
Flat voice acting. Antagonist's voice doesn't match the character and fails to display pretty much any emotion. Jotaro is voiced well, but pretty much nobody else stands out. The anime paid, however, surprising amount of attention to foreign languages, which (to my ear, at least), sounded like they were spoken by native speakers.

Characters:
Since the whole thing is centered around fights, they do not really change over time (no time for that), and more like superhero characters. However, they do their job fairly well, so here's that.

Enjoyment:
It was interesting to see one of those older anime that depicts events without kid's gloves, where anyone can die, and no person on the screen is "safe" from something happening to them. This was refreshing. The story starting in the "middle" of actual story was a bit confusing, however.

Overall:
It is definitely worth checking out, but I would not say it is a "must see" anime. It is worth checking out for the art style, violent fights, which can be very imaginative.
