I've been racking my brains for a good climax, but man. I got nothin'.

The problem is the whole damn point of the movie is returning the skull to the temple and there is no payoff for it. At least not one that works for me. If it was the only way Jones could save Ox or Marion or whatever, then maybe it would have some impact.

It would be great if Spalko was actually trying to get all 12 skulls for her use to rule the world through their brain control instead for her "I vant to know" quest for knowledge. She puts the last skull in place and together the mind control power of all 12 skulls melt her brain and she dies like General Grevious. Meanwhile Mack is stealing treasure, it sets off a booby-trap (It's a trap!) and the walls come a-tumblin' down. Everybody run for your lives!
