Spielberg gets it; Fans don't

A little theater history here: 3 is the magic number (in point of fact, it's a universal truth). 3 act structure reins and so does stories told in trilogy. Spielberg understands that very well. Indiana Jones and the Crystal Skull IS NOT PART OF THE TRILOGY. That's done and over with two hits and a miss (1: hit; 2: miss; 3: homerun).

SPOILER WARNING: PLOT POINTS ARE GIVEN AWAY BELOW...

IJ&tCS isn't the beginning of a new trilogy, nor is it a stand alone. It is a bridge. Because it is a bridge, it tips the fedora to the first three and sets up the future. You've been given a peak at the new direction of the IJ franchise and it is a clever one.

Indiana Jones is about history; about ancient legends.
Mutt Jones will be about the bizarre; about urban legends. Hence the aliens (and not just space aliens, but interdimensional ones).

Indy is a relic that belongs to the 40s and 50s. He, nor any archaeologist, is going to work in the 60's.

Indy is loosely based on Alan Quartermain, of King Solomon's Mine fame. He is meant to be a hold over of the previous generation. The purple haze of the hippie generation is too far beyond that era, so this movie sets up the next movies as a precursor of the X-Files type stuff.

I really enjoyed the movie. Yes, some big plot holes, yes, a bit over the top (as is common for Indy movies). Rather than annoyed by the thought of Indy as an OSS agent, they gave him a Casablanca riff (Rick is cut from the same cloth, but he does his bit for flag and country) and it worked for me (interesting possibilities for books, I'd think). A nice melding of ancient legend and urban legend. I would have liked Mutt to "get" stuff that Indy didn't, but we can't have everything.

Even Mutt's name is a wink to expect a melding of ideas. Not sure why the whip wasn't used much, maybe Ford can't handle it anymore.

B+
