i don't remember much of Steel so i can't really comment too much about that film, except that i do remember not liking Shaq in it.
Elektra, wasn't terrible but wasn't great, pretty average.
X3, no where near as good as the other 2 films, so many things wrong with it, mainly no Gambit, too much Wolverine and Storm and not enough Kitty, but still some good ideas, def not the worst film ever.
Batman & Robin, at the time i loved it, i was about 10 years old though.
now i can't even watch the whole thing without turning it off half way thorugh, but it is Batman and Batman kicks ass.
Catwoman, i was expecting good things from this movie, (i didn't see previews or anything like that, i just knew it was Halle Berry playing her and i thought she was a good actress) but this was a disaster, completely changing the charcters origin, terrible, terrible terrible.
Catwoman by far.
