I've enjoyed the trailers I've seen for this Summer's movies. Wolverine looks big and stupid and fun. I've really enjoyed the Star Trek trailers, and love the concept of the movie. Up is, I've been told, a documentary about me when I'm an old man, but with my current personality.
But none of them have given me that jump-up-in-your-seat, giddy, "I want to watch this again right now," thrill that the above trailer did.
I didn't realize the real Sam Raimi had gone anywhere, until we got him back.
