I hated that movie. It was putrid.
The action scenes were WAY over the top. Now, I know you're thinking that every Indy movie was like that, but the older ones at least looked feasible. You watched the action scenes and thought, "I know that could never really happen, but that'd be cool as shit if someone could pull that off." With the Crystal Semen sequel, the action scenes were "no fucking way. What a horrible idea."
What car fucking goes rafting after it plunges into a river? Oh right, the tree broke its fall.
I don't blame Lucas and Spielberg. They knew it was another asshole that farts money.
