I think the melting faces, the airplane brute in Raiders (Pat), and the big Thugee (also Pat) were the best deaths. Melting faces win from Raiders.
Forestal's death also rocks cuz he sticks around to give Sapitol a scare in Raiders. So maybe thats the best death cuz he comes back in a vengence later!!
I thin Vogel's death is the worst on screen death ever. Crappiest fight and crappiest death scene. And he wasnt that bad of a character to boot. If Spielberg would have stopped drooling over shooting the Ford Connery character scenes...maybe we could have had some decent action in Crusade.
Here's hoping Spielberg has that all out of his system for Indy 4. But with Shia in the picture.....
