I hardly ever hear about people who go in to a movie expecting it to be crap and then coming out thinking it was totally awesome...
hmm,
I always thought it was the opposite, if you're not expecting much from a movie but turns out to be half way decent, then you're more likely think it was really good, as it shot way above your expectations. Same applies for a movie you thought was going to be amazing, but only turns out to be good, it'll strike too low and you'll think it was crap.... or at least not very good.

"Earth? Earth-with-nuclear-weapons Earth?"
"Yes."
