just came back from a screening. and i gotta say i don't get all these critics who've been trashing the film. i think many of them are simply over-exaggerating.
i will say that BvS is somewhat messy in parts, and the 2nd act feels like it's treading water before the inevitable showdown. so that can indeed be chalked up to unnecessary bloat.
but if anyone tells you the filmmakers don't get superman as a character they're just plain misreading the film. if anything, i liked the way supes is portrayed here. this is not a superhero who has figured out the "hero" part entirely. he's a work in progress and he knows it. BUT clark/kal-el has learned things since the last film and he's shown to be learning throughout this film... what it really means to be a hero, what it takes, and the sacrifices that come with it. i actually think snyder/terrio made supes quite a sympathetic character.
and this is clearly juxtaposed against his polar opposite in batman/bruce, whose worldview and values are as cynical and unforgiving as clark's is hopeful and forgiving. what I like about the "versus" here is that it does not just stand for a 2-hour superhero beatdown. it goes out of its way to establish the ideological, emotional and (to a lesser extent) psychological differences of these two men.
i could go on, but bottom line is, i really enjoyed the film. it certainly has flaws, some i found particularly clumsy and odd. but nothing really fatal that would qualify this film as "bad/crap/garbage/etc". not even close. the principal cast is great: batfleck stands out, WW gadot is cheer-worthy in her short action scenes, and cavill is fine. he certainly isn't wooden, he's just given slightly less opportunity to shine. there are some beautiful emotional moments in here. one in particular concerns how they end their battle, and as irishjedi (if i'm not mistaken) pointed out, it is a rather elegant resolution.
also, the action climax isn't an exercise in overkill like MoS (which I liked too). it lasts just long enough to not outstay not its welcome, and has enough variety in the sense of who's-doing-what-to-whom so it never feels repetitive (again, like MoS).
lastly, the cinema i was in gave a resounding round of applause at the end of the movie. which is rare, if you know anything about asian audiences. take that as you will. your personal mileage will of course vary, but i say, don't listen to critics who don't seem to be able to separate their personal issues from the viewing experience.
