As a fan of quality writing, I'm reading "Writing for Comics with Peter David". Even as a "DC-guy" (not a "Marvel guy"), I have tremendous respect for Peter David and his work.
One particular part of the book relates at length to the Indy trilogy and its strengths and weaknesses. One part has been sticking in my mind and I thought I'd share...
For that matter, Marv Wolfman pointed out that if you remove Indy from the story, there is no difference. If Indy isn't there, the Nazis go to Marion and get the headpiece, use it to find the Ark because they're digging in the right place this time, put it on the sub, bring it out to the island to open it and they all die. The end.
Makes you think...
