Batman vs. Superman
Loved it, for the most part. It has its problems, and I can see why casual audiences might find it confusing and messy, but as a long-time reader of DC comics, I was most pleased.
Allusions and full disclosure of other elements of a broader DC Universe abounded. The flash-forward that Batman is given by Metron(?) to warn him of an Injustice-style possible-future in which Superman rules the Earth with an iron fist was one of my favorite moments. Seeing the other heroes who will be a part of the Justice League in later films was pretty cool, too.
Wonder Woman stole the show. Everything from her attitude, to the demonstration of the full range of her powers, to the way the movie's soundtrack changes drastically when she launches herself headlong into battle was too perfect.
As for the bad...
Batman killed a ton of people, used guns a little too much (which is at all, really) and most of the flashbacks for his origin story were completely unnecessary at this point (if you're one of the 2-or-3 living beings on this planet that doesn't already know that Batman's parents were shot dead right in front of him as a young child, you're not going to pay money to see a movie where Batman gets top billing).
Jesse Eisenburg's portrayal of Lex Luthor was off, IMO. I much prefer the characterization of Luthor as a cold, calculating, amoral bastard who's always the smartest person in the room. Seeing Batman fooled in any way by the silly and awkward geek that Luthor was in this film didn't jive.
Doomsday should have had his own film, rather than being tacked on to the end of this one. He's too big of a deal to not have a setup like he's had in the past, where dozens of damn-powerful heroes throw themselves at him and are almost instantly stomped into the ground before Superman finally ends things by giving his life to bring the battle to a draw. The fight was really incredible though, at least.
Still, a very enjoyable movie for a DC geek like myself.
