Dungeon ni Deai wo Motomeru no wa Machigatteiru Darou ka IV: Shin Shou - Meikyuu-hen

The season overall is mediocre at best. The story and conflict building from episode one feels flat and too straight forward and too fast to be felt like a progress that built up towards the climax. TBH, it felt like with the story telling as it is, the two parts of the season could be summed up in two episodes of separate OVA (given the first part felt more like a filler). Or rather having one whole season with 12 episodes of the second part of the season with proper story, character, relationship, and tension building would be preferred.
If you've watched all the previous seasons ... however, feel free to watch (and get disappointed) this one as well.

Production quality (art and sound): 8
The production quality is not bad, nothing stands out, but pretty nice. The picture is good, the motion is good, felt natural, and makes sense. Even when they just throw out some english non-sense doesn't feel so bad. It is consistent as well. No quality drop whatsoever. The sound is not as satisfying as the art but doesn't feel off.

Characters: 3
Every character is unique, well thought and has a role to play in the season. No character was left out. And the way the story was told were also balanced, making sure every main character has the same screen time. I'll give them that.
The bad, however, is that there were quite the inconsistency among almost all the character and the relationship between them, giving the later was not as prominent as the former. At one scene, one character is portrayed to be strong, but at the next scene (of the same episode), the character would be portrayed as weak.
If you want to make a character relatable, want the audience to sympathize, to feel the story, to be immersed, then a character has to be consistent. This is particularly troublesome because the inconsistency can be found literally in one episode. Sure, not anyone can be strong at all times, but there has to be a reason and a regress as to why the character is becoming weak. The author and director need to understand that just getting instantly stronger from a weakened state should not be the whole development. The way the character overcome their weakness should be an inseparable part of the development. I found this unbearable to watch.

Story: 1
The story telling is an absolute bore. No surprise whatsoever. The plot is straightforward, no turning back, no back story, nothing. Like straight from an elementary student's writing.
To make it even worse, every episode feels the same. Even the two parts of the season started the same way with some premonitions that something bad will happen. The story of each episode is quite literally: the party encountered danger, one character showed their power, the problem solved. Then another problem appeared which needs a character to get stronger to solve it, the character gets stronger, the problem solved. Not even once that it felt like the characters is faced with a problem that is likely to cause them harm. Deus Ex Machina done wrong.

My oh my, what the hell did I just witness.

I've been watching the series season a day and no surprise- it was great. Loved the first 3 seasons and was ready to be blown away once again. It started great, first few episodes were a joy to watch. It was action filled, it felt more compact and made me thrilled for more. But then..
Boom. They start explaining the ENTIRE past, plot and everything we have already seen with our two eyes. It lasted for such a long time that for the first time, I almost fell asleep durning this shi-.
The plot was idiotic and ... easily avoidable, which just pissed me off even more. Why? The pace, the writing, everything.

I pray that they fix this at least a little in part two because otherwise be smart and finish this anime after season two.

When this series first started airing I was intrigued. Here was a story that wasn't nothing new in the way of anime stories go, but it was seeming self aware and ready to take strides towards creating a story that had depth, development and importantly plot. It introduced a MC that was cognizant of his inadequacies and created a goal to strive towards.

However now here we are in S4 and everything that S1 started, this season killed.

The MC is still weak minded (But hey don't worry about power up because he's got "God Mode" to help him level up), whiny and incompetent and sorely ... needs saved by humongous amounts of plot armor. They have thrown out the actual plot in lieu of fan service and tom foolery which of course, keeps up with the status quo of the garbage already out there. There is no story line other than the wash, rinse, repeat story line of the weekly big bad.

As far as those mysteries they put out there: Yeah forget that we've got HAREM and BOOBIES.

Seriously, for a series that had such a good solid start, it sure became a dumpster fire in a quick minute. Not surprised, but highly disappointing. Bring out the rest of your dead, then drop them and this one in the funeral pyre because they are all victims of the dying anime industry.
