Ash and I went to the theater to see Indiana Jones and the Kingdom of the Crystal Skull. That's a pretty big deal as I usually wait for DVD releases to watch movies, but in the case of big Lucas movies and all the Harry Potter flicks I make an exception.
I try to never spoil anything, so don't fear. But I will say that I found the story a little weak in this one. Sure, each Indy is "out there" as far as reality is concerned, but they still somehow make you believe pretty well. I had a tougher time in this one. That said, the acting and the production quality is very good. The action is somewhat believable. Perhaps most importantly, I saw good potential for some really fun Disney rides.
All in all, I'd recommend it, especially if you normally enjoy all things Lucas. I do, and I had a fun time. It's so easy to be critical when we have such a large body of work to judge it by, but I'd say it's good. Maybe not quite as good as the other three, but close enough to warrant the Indy name. Probably the best humor of all three, too.
