I posted this in another thread too but here's my thoughts:
As a huge fan of the previous three Indiana Jones installments, I gave no thought to the countless sub-par reviews I've read/heard going into this movie. Seems this movie was just destined to draw unmerited criticism from those looking for replicas of the prior three, which of course, it has. I went with no expectations and was eager to see whether Harrison Ford and Co. could affectively portray a significantly older Dr. Jones without compromising the overall legacy of the series. Here's what I got out of it:
From a nostalgia P.O.V., they certainly tried to incorporate many of the old familiar Indy trademarks. Without giving too much away, there's some fun references/revivals of older characters either in discussion or in person, i.e. Marcus Brody.(sorry if that's a spoiler but he's been dead for like 15 yrs) We get the old map with the plane flying to a red dot bit, which I always liked as a kid. And of course there's plenty of Indy's trademark quips along the way(often so bad they're good) There's more, but I'd say they did a good job touching on the old movies without dwelling/relying on them.
The characters were lacking in some spots. The previous movies all had established/interesting enemies; Belloq(the french guy,) Walter Donavan, the Nazis, Dr. Elsa Schneider, and the guy who pulled your heart out. Cate Blanchett failed with this task, as did incorporating the Soviets. The character of Mac also seemed uninteresting and perhaps underused at times, and another new character, Ox, spent most of the time doing his best impression of a homeless person who's lost his marbles. Indy's new sidekick Mutt was hit or miss, but mostly hit considering there just wasn't anyone else on screen doing anything cool a lot of the time. Overall the supporting cast was my biggest problem and left me wondering where was Short Round, Salah, and just how big the paycheck needed to be to get Sean Connery's old ass to sign on.
The action sequences were fine, for the most part. Indy can still throw a punch and look convincing doing it, yet his whip-work was largely missing throughout. There were some cool action scenes peppered throughout the movie, but there were certainly some that were a bit hokey(Mutt swinging expertly from vines in the jungle was kinda stupid) Despite a few cheesy action scenes I'd say an older Harrison Ford looked just fine to me.
The plot/storyline was interesting. It certainly touched on the sci-fi end of things, which was fine for me. It was by no means as well developed as the other films, but it held my interest up until the ending, which bordered on ridiculous. The main content of the story left me feeling stuck in no-man's land a bit. I felt like they gave us enough info to be curious and have questions, but didn't go all they way with it and completely satisfy the curiosity. In the end the conclusion seemed like a combo of National Treasure II and Stargate.
I guess this probably reads like I didn't enjoy the movie, but I definitely did and would recommend it. It may not scratch all the old itches but it certainly seems like a worthy addition to the series. I'd say 3 stars with an upside, as I can see it getting better with more viewings.
