Had an interesting conversation over drinks last night about trailers, and the relationship of the trailer to a film. The discussion spiraled outward tangentially from an earlier chat about the Watchmen film adaptation, wherein someone in my group commented that the film's initial trailer (seen here, for posterity's sake) was better than the film itself.
So, I pose this question to you forum-goers: What trailers ended up being better than the movies (or games) they promoted?
A secondary question, with context: Someone in our discussion last night suggested it's good for a trailer to be better than the film, because that will entice people to see movies they otherwise wouldn't have watched. What are your feelings?
My submission to the conversation is the first one that comes to mind. Prometheus.
