Overall, Lucas & Spielberg did a great job w/ the homage to '50s B Sci/Fi films. The Cold War stuff was great w/ a nice little comment on current political issues & the importance of academia in terms of our ability to speak up about the problems w/ the government... something the '50s films had to keep rather veiled under the watchful eye of Joe McCarthy. As bad as things might be under GWB, @ least Spielberg & Lucas won't be getting blacklisted.
Of course, there are a few holes in the plot, but having seen more than my fair share of the '50s B movies, I'm willing to accept the problems as part of the genre. My only real complaint is about the use of CGI ants. The snakes, the bugs, & the rats were all real in the 1st 3 films... I suppose it would have been tough to find the millions of real ants they would have needed though. Overall, there were many stand-out scenes like the sword fight, car chase through campus, the nuclear test site, the waterfalls, etc, & as Jean claimed, Marcus Brody was used to great effect. Stand out performances by Harrison Ford, Karen Allen, Jim Broadbent, & Kate Blanchett are all noteworthy. I was a little underwhelmed by Shia LeBeauf though. He's a lot better than Sean Patrick Flannery, but he's no River Phoenix. Overall, I'll definitely be seeing this one again soon. (As for the animal kissing the girl, apparently Nim is kissed by her friend, a seal.)
