I see why people like this show for it's setting, but I only enjoyed watching FMA:B for about 5% of the time.
- The main characters lack depth, growth and consistency. I feel like most of the main characters are almost entirely the same, from beginning to end. The same motivations, the same actions. There are a few exceptions, but that is nowhere near enough to redeem the rest.
-- Ironically, the side characters are WAY more fun / interesting.
- The plot is predictable from beginning to end, with the exception of some minor plot twists. Moreover, it's quite THIN. In my opinion, it really felt like nothing happened for about 40 episodes, leading up to the predictable finale of the show.
- As a result, pacing felt horrible. I found myself sitting through a few dozen episodes, because I knew what was coming and it just kept taking longer and longer.
- The art is sometimes incredible, but almost always boring. Mustang's fire blew my MIND at times, but the endless still frames and unimpressing visuals really tired me.
- Combat feels very weird for power level / plot reasons. The main characters have so much power, yet barely use any of it, often times. (What is the POINT of hand-to-hand combat if you can crush people between brick walls?)
+ The main redeeming part of this anime is the power system. Such cool intricacies, variations, flavors, visuals. And the underlying mechanics are super interesting!
I restarted FMA:B three times after dropping it before. I sat through it because I wanted to know why it's so loved. Sadly, I did not enjoy it and I would definitely not recommend someone watch 64 episodes of it. I found it VERY unrewarding, the whole way through.
