Just got back from seeing same. Good flick. As good as the original three, after a 20 year lapse. Harrison Ford looks a bit older, but still handles the daring do. The rest of the cast is good too. Lots of good action scenes, lots of good sight gags. It's pulling a good crowd, theater was full on the third night in a small town.
Disregard the negative reviews that have been circulating on the web. This movie does exactly what an Indiana Jones movie ought to do, and does it just the way the first ones did. Much better than the add on Star Wars movies did.
Indiana Jones is his old self. He picks up a teenage side kick who gets good lines, and acts them well. There is an evil villian, played by Cate Blanchett with style and dash. It's a corny role, but she handles it properly. The special effects and stunts are lavish and good.
