I used to love movie trailers. Nowadays they give the entire plot away, show all the good parts (or worse, show good parts which are not actually in the movie), and are preceded by over-long and pretentious American Express commercials that I would pay money to avoid. The voiceovers also all seem to be by the same two men, Cheery Optimist Guy and Dramatic Bass Voice Guy.
With that said, without the suffering and pain administered by those bad trailers this send-up would not be as funny. (Origin of the video explained here.) For comparison, the original movie trailer is here.
