This has some predictable and fraying threads for plot lines, and it struggles to cram enough for two movies into one. The surprises in the good action scenes don't overcome those flaws. However, my 10-year-old son loved it, which I'll get to in a bit.
So if you're under 16 or an Indie Junkie, go. If not, wait for the video, because it runs like a long trailer that does little more than introduce the new lead actor for the franchise. Here's why:
The two-movie-in-one cramming thing leaves us with: -- bad guys and artifact guards who disappear and reappear with little explanation; -- so many political statements to balance each other that the movie avoids making any statement that's meaningful or strong; -- explanations of archaeological details that make what might be interesting boring; -- a crazy professor character you want to care about but can't.
On the flipside, here's why you'll want to rent the DVD: There are absolutely enormous and unmistakable links to major Spielberg/Lucas enterprises from decades past. They seemed to go down memory lane and revisit their old projects to put them in hd. So long as you were born pre-1996, you'll spot this trend in: the skulls, the teenie-bopper hangout, a jungle chase scene -- just to name a few without spoiling anything. Second, Ms. Allen turns in the spunky performance you wanted. Third, it's not the sugar-coated, cloying stuff of the worst episode ("Temple of Doom.")
If you were born after 1996, who cares about plotline. It's all fresh meat and plenty of action -- and opportunities to get that popcorn refill without missing a key scene.
