Okay, so it's too late to predict how good or bad Iron man will be, but there's still plenty of others to make some guesses about. He's my unsolicted predictions (in order from "cool" to "sucky"):
Walle (totally cool)
Hellboy (way cool)
Narnia (Narnia will never be "cool", but there will be a story there)
Incredible Hulk (sort of cool)
Indiana Jones (not cool)
Speed Racer (daring, but never hits it's stride)
Kung Fu Panda (well, I like the character design... er, hmmm...nope, that's all I got)
Get Smart (the first trailer looked decent, and it's gone downhill from there)
The Spirit (oh god, don't give FM any more money!)
Journey to the Center of the Earth (complete drivel)
I guess I should elaborate on the Indiana Jones ranking... in my view, Raiders was the only good IJ movie, the other 2 are pretty awful. Also, I don't like that Transformers kid that's in it.... not. at. all. On the other hand, Karen Allen is in this one... most likely the main reason that the first one is so much better.
