I paid my $17 and watched X-Men 3 on the opening weekend. Liked it. I know all the critics hate the "let's throw more special effects at it" style of sequels, but I happened to like all the new mutants. My favorites? Iceman/Bobby Drake (finally makes a real appearance) and Juggernaut/Cain Marko. Don't get the wrong idea - I'm not a comic book reader (not that there is anything wrong with that). I learned everything from the Saturday morning cartoon when I was a kid. That and the Internet.
I also watched Steamboy - an interesting Anime movie about a young inventor caught between the power struggles of his own deranged relatives in 1860's England. Watch it if you can find it, if only for the breath-taking hand-drawn animation. Features the voices of Patrick Stewart and Anna Paquin.
