I guess Spielberg and Lucas would agree with me that the worst Indy-Scene is the "boat-out-off-plane-jump" in "Temple". This is a little bit to much. It's over the top-action. Indy in action means REAL stunts like in "Raiders" and "Crusade".
I'm very happy that they do real stunts in "Indy IV" too.
But don't get me wrong. As you all know I love ALL Indiana Jones-Movies like no other.
