It's sloppy but good. I don't know how a trailer could do well setting up the movie.
Can we please stop making Bruce's parents' death scene and his falling in the cave of bats included in every variation of his on screen.
Fight scenes were fantastic.
Wonder Women's theme music is GREAT.
I'm so tired of Snyder purposely muting all the color in scenes. It would be fine in instances. But, for example, there's a shot of really lovely wheat fields, and it's just so obvious that the color has been shifted from something that should be a brilliant gold color, but now is cold and a blah tan color.
Irons was sort of a wasted version of Alfred. Not bad, but just ho-hum.
Whoever animated Doomsday gets an F on the look of the character. It's like as mentioned before, a LotR orc crossed with Abomination from the Hulk movie. The CGI is great, but the look of him is meh.
I'm on the fence on Lex, and in part I think it's done on purpose, because this is Luthor lite, sort of, but you can see where they're going with the character by some of his behavior.
In retrospect, it may really pay off in showing his misguided evolution and psychotic fixation taking him "down the rabbit hole" because he clearly is envious of Supes power, and his actions stem from thinking everyone else thinks like him. Hence, such power is such a threat.
He's very much a character in formation. Batman wasn't Batman in Batman Begins, so I don't know why so much automatic criticism for portraying the rise of a super villain?
So,
The scope of the story is huge, really, and I wouldn't say it is epic, but I think it was a better offering than anticipated. I'd give it a low B+.
