I've never got the Temple of Doom hate.
I mean, sure its not as good as the others, but its still a good, fun movie. In the end, that's really about all I ask for from Indiana Jones. Anything more is a bonus.
And I can't say I'm THAT surprised with any disappointment concerned Crystal Skull. This definitely is going to have a case like the Star Wars Prequels here expectations reach a dangerous level for many people. Course, in this case, if its terrible one can't just blame George Lucas, since Spielberg and Ford were supposed to be holding out until it was 'perfect' to do it.
