I have to go very much out of my usual formula to review Kekkai Sensen because it is a rather complicated case This is also going to be a very quick review seeing as the shows flaws are huge and can be summarised quickly. For starters the show looks AMAZING and is in my opinion the best looker of spring 2015. What truly sells the visuals is the directing. It gives of a sense of uncontrollable energy and fun which upped the overall score for visuals quite the bit. The soundtrack is also pretty sweet. I actually found myself listening through the opening instead of skipping through it just because how amazing the song is. Same goes for the ending. Simply put very listenable. As for the rest of the soundtrack your usual mediocre background tracks sprinkled with some great standout tracks inbetween for good measure Talking about the story is the hardest part. After watching each episode I had myself thinking Man that was a great episode. The comedy is on point the plot was amusing the characters were entertaining the shows structure was original see recap episode 10.5 etc.. Overall a great show And this worked out very well for the first 7 or so episodes but after that point one thing in particular became very apparent. Every episode feels like a separate work on its own with only the main cast and the location to tie them together. There is no semblance of a story at all. One episode ends with the main cast looking over an army of demons the next has our main character bribing a mushroom with hamburgers. What little there is of a story is basicly New York is surrounded by a fog that has connected the demon world to the human world. How? Were never told... In this new New York monsters and humans have to coexist. In the midsts of all this our main protagonist has decided to move to New York where after a series of coincidences begins working for Libra an organisation centered around keeping threats at bay. Aaand thats about it... There is hinted towards a story from time to another the world is threatened by vampires Leonard has selfdoubt issues Libra is a group of misfits trying to make a living etc. but it is all so very subtile until it is slapped straight in our face like a plot twist. The thing is it is not a plot twist just a speedy plot point. My major gripe here is that it feels like the story is being sidetracked for comedy or rather filler episodes which have no place in a 12ep show. It could have been along the lines of character centric episodes but the aforementioned filler episodes are merely arbitrary comedy skeets... You could make the argument that Kekkai Sensen is a slice of nothing ever happens comedy and should be judged accordingly but the show occasionally tries hard to get its story across the board and thus has to be judged as so. If Kekkai Sensen had been something along the lines of Kara no Kyoukai or Haruhi Suzumiya where the episodes were not released chronologically then the aforementioned ridiculously bad pacing and poorly tied together story could have been due to me just not understanding the plot due to unconventional conveying but I cant even put the blame on such a scenario. As for the characters there are just too many of them. But they all have two things in common. They are all based on character tropes and they are all ridiculously two dimensional. I could go in depth or as far as possible with the rather limited personality each and everyone were given about each and every character but instead il just list a few of the main. You hardly need anything more than this before you know everything about the characters. You have your run of the mill easygoing main character Leonard Watch the asshole Zapp the tough but straight guy Klaus deluded villain Femt obligatory love interest Mary/White and the whimp William/Black. To the shows credit episode 11 is pure characterisation telling about the past of some of the main characters but it is very much a too little too late scenario. Instead they should have put this episode closer to the midpoint. Indeed it could take some of the suspense away from the anime but at least the story would have been a tiny bit less nonsensical. To summarise Kekkai Sensen is a show that had a lot of potential. Every episode in and of itself were great but the episodes themselves had no semblance of connection. The show falls flat on its face due to horrible pacing limited character characterisation little to none character development and a too short of a runtime. Say if Kekkai Sensen had received a 26 episode runtime the MABY the characters and the story would have had the time to be fully fletched out instead of being the rushed mess that it is. The shows main selling points are definitively the animation music and comedy and with the exception of the aforementioned being great there is very little to talk about... Kekkai Sensen could have been great but ultimately is a rushed mess and the final episode being posponed indefinitely further underlines that statement
