I actually thought the first half of the film neared perfection; the last half . . . well, particularly the last third lost a lot of credibility for me. And (erm, SPOILER) Spielberg's overly long, hackneyed, "happy" denouement gave me a toothache. Whatever the flaws of the inferior Temple of Doom, the thing ended tightly. This one belabored the whole feel-good, family-value-ness of it all, and it just annoyed.
I enjoyed the period setting, and kind of wish they'd gone further with it. Seeing the aging boomer among gen-Y extras playing an aging WWII hero among vibrant socs and greasers was a real pleasure, and it might have been interesting to go further with the McCarthy-esque paranoia, maybe even throw some Beats and the like in to broaden the palette. But we can't have everything. It should be enough that they utilized Ford's (relatively few) physical limitations well, that they gave him an interesting (and, I agree, under-utilized) foil in Winstone, and that they played on the notion of Jones' becoming a relic without belaboring the issue.
The first major set piece felt refreshingly analogue; I wish the rest of the film had followed suit. Tthe chase in the jungle, with Shia LaBoeuf's CGI enhanced jeep straddle
and swordfight was too much for me to take, and signaled a slow
downward spiral (with a few notable upticks) for the film. LaBoeuf's
Spiderman-like swing through the jungle was unforgivable. Suspension of disbelief and Rube-Goldbergian plausible impossibilities are one thing (possibly THE thing), but once it becomes a cartoon (rather than a comic book--important distinction), I lose interest. Not that I don't like cartoons, or even live-action cartoons (Sky Captain, Sin City, Kung-Fu Hustle), but that's not what I come to Indy for.
But as empty cinematic calories go, it could have been a lot worse. I was entertained.
