Here are a few of the things that bugged me immediatley following my first viewing of the trailer said in order of when they appeared in the trailer.
1) Why is Lex Luthor so excited/ animated to see Clark Kent, and Bruce Wayne together?
Unless he knows both of their secret identities it just doesn't seem to make sense. Clark is only a reporter for the Daily Planet. He's not even the newspaper's top reporter. What is Lex's motivation to have the two together in one room?
2) "What a grip, you wouldn't want to get into a fight with this guy!"
Is this line on the nose or what? Not only is it extremely hammy, but the line betrays certain things about how Clark typically handles himself. Clark is supposed to hold himself completely opposite to how Superman does. He should be meek, with little eye contact, and he would ensure to be the weaker of the two hands shaken especially during an interaction with someone with a huge ego like Lex. A better line would involve the two shaking hands and Lex commenting on how a professional man needs to have a firm handshake to get anywhere. Remember Lex thinks of himself as the smartest person in the world. He needs to look at Clark and think that there is no way that he is Superman. From his point of view it would make no sense for a godly alien to hide as a meek, low payed reporter.
4) DOOMSDAY!
Okay, am I the only one who thinks it's a little early for a character like doomsday to appear? I mean he holds the honour of killing superman, I kinda wonder what he's doing as a secondary character tacked on at the end of the trailer. Also why does he look like a cross between abomination from "Incredible Hulk", and a CGI'd Dwayne "The Rock" Johnson from "The Scorpion"?
5) Batman almost dying
This is really nitpicking, but I feel as if, if batman was so close to death he would be trying nearly everything in his power to get out. He would pull out a batarang or something to try and cut himself out. He would be completely serious through it all. One thing he wouldn't do is stop look and the camera and say shit. It just seemed way too hammy and out of character to me.
