I can pretty much guarantee you that everyone that considers FMA:B trash watched the 2003 anime first. The 2003 anime has tons of pointless filler, lots of weird/completely trash characterizations, an absolutely batshit ending, a waste of Hohenheim as a character, and so on. It does some things right, like its great tone (for the most part), its soundtrack (though I prefer Brotherhood's myself), and it's great explorations of the homunculi (I really enjoyed the "homunculi were human in the past" plot point). But Brotherhood is top fucking class shonen, and anime in general. Other anime do things better without a doubt, but I've been able to show Brotherhood to all sorts of non anime fans, and every single one has loved it. It's approachable, fast paced, and fun as hell. You can like your more moody version all you want, but I'll take a more upbeat (and also faithful) adaptation that accomplishes exactly what it set out to do over a darker one that flounders completely in the last third (and especially that movie, jesus christ what a shitshow) any day.
On topic though, Evangelion Q/3.0. A movie so fucking awful it more or less killed my love of Evangelion. There basically is no plot, it's a just a bunch of scenes and nonsensical character interactions strung together with periodic and obligatory big and crazy action scenes with no narrative weight and way too much 3DCG. It basically sold itself on "Kaworu and Shinji fanservice the movie" and somehow people ate it right up. It shits all over Kaworu's character too, but tons of fans don't give a shit just because of some amped up homoeroticism.
And I've seen all sorts of "well see Anno was just subverting your expectations after 2.0 was a more straightforward action movie!" No, he subverted my expectations by making a shit movie. I can handle subversions, otherwise I wouldn't like Eva in the first place. But 2.0 was a competently made film that offered a tantalizing chance at a brand new take on Evangelion with its ending, even if it had to take some hits in character development of the side cast to get there.
3.0 has no development of anybody whatsoever, no world building besides "shit's fucked and I'm gonna be real vague about everything", crappy, pointless action scenes with stupid shit like Unit-02's cat form, the pilots conspicuously staying 13 years old because of totally not brand recognition (and creepy Japanese obsession with youth), every single character being a dick to Shinji for no reason ("an emotional 13 year old made a decision that I cheered him on to do? well fuck him he sucks and I'm gonna keep in the dark because reasons"), and so on. Nothing fucking happens in this shit movie, it's just flash that doesn't even succeed. At the end of the day we don't know shit about NERV, Wille, the world at large, what is anyone fighting for, why was Kaworu even here and what was he all cryptic and shit about. What was the goddamn point?
God. Fuck this movie.
The only redeeming characteristic is Shiro Sagisu's soundtrack, but in my opinion it's not even close to as good as 2.0's soundtrack. There's more music, but it's all overly bombastic and a lot of it screams pretentious. Which fits the movie I guess.
