Yeah, I'm going to echo all the MoS responses. Not that the film is bad (I really liked it), but Trailer 3 is just on a whole other level. It works as such an incredible summary of Superman's essence that there's really no way any film could stand up to that. It's easily as good as the one-page Richard Donner-penned origin in Action Comics from a few years back, or the opening page of the first issue of All-Star Superman.
Alien 3. If it wasn't the whole "On Earth, everyone will you hear you scream" schtick, the later trailers implied that it was going to be a nonstop action-fest with Ripley leading the prisoners. The final film is anything but, and more of a return to the original film. I'd also throw Prometheus in, because all that retro-Alien hype just dissipated after watching the first half-hour of the film.
