Watched Iron Man 2 and Superman/Batman: Apocalypse (yes, it isn't out yet. It'll be out next week) last night. I was really looking forward to both since I was a big fan of their predecessors (Iron Man 1 and Batman: Under the Red Hood), and both disappointed me. I found Iron Man 2 to be a really uneven movie, with a decent beginning and a decent conclusion but a middle that's a little dull. Iron Man 2's story felt really loose and a bit impenetrable compared to its predecessor and the jokes largely weren't that funny (the best material was when Tony and Pepper were together and that didn't occur that often). The action scenes were ok, but I never really cared about any of the villains. The movie in general felt more like a setup for the Avengers movie than an Iron Man movie.
As for Superman/Batman, I don't know why Batman's name is even in the title: aside from a nice little scene between him and Darkseid late in the movie, he doesn't really do anything in this movie and he's even more of a jerk than usual. Neither does Supergirl, for that matter, until the end and this is supposed to be her story. I really didn't expect to see Wonder Woman in this movie, but I felt that she really fit well. Unfortunately, like most Superman/Batman team-ups outside of the Justice League series, Superman tends to dominate the show since the writers feel the need to have a threat worthy of his ridiculous array of powers that get boring quickly (there's only so many times you can see Superman using his heat vision or punching a guy before it gets old). Superman is a boring character IMO outside of the Bruce Timm animated series, and he's not terribly interesting here either despite dominating the show. And no Michael Ironside playing Darkseid=FAIL. The artwork in the movie can also get a little poor at times, especially the lips on the characters that make their faces look really goofy. Overall, the movie's ok but it pales in comparison to the high standard set by Under the Red Hood.
To make matters worse, the next DC animated movie's going to be another Superman movie. *yawn* Guess I'll put that up there with Green Lantern: First Flight on the list of DC animated movies I can safely ignore.
