Double Whammy

When you watch a movie you've cherished since childhood but haven't seen since then only to find that not only is it not as good as you remembered but also that you have now ruined the memory you had of it.

Origin:  Rewatching Rush really was a real disappointment for Pete.  He really loved his memory of the coolness of Jason Patric and the hotness of Jennifer Jason Leigh, but watching this film again really ruined that memory.  He also realized how much he didn't like the film.

Usage:  I rewatched Ralph Bakshi's Lord of the Rings and, man -- what a double whammy.  

First Used:  Rush
