TBH I actually like all four of them. Granted Kingdom of the Crystal Skull is vastly inferior to the first three, but even that one had its merits. The fridge scene didn't even bother me as he has survived ridiculous situations like that before. Though I like to pretend Shia Labeuff doesn't exist.
So much has been said about the first three that I have little to add. Just... Go and see them. Oh and as a horror fan, Temple of Doom definitely has for me one of my top ten kills in movie history... All the heartless people in the world know what i'm talking about
