Man, I haven't chimed in for a while.
Well, the "big" movie-- or the one that's stuck in my head, was "Dick." Did I mention Dick before? I forget how I heard about it, but it was sort of a logical extension of "Clueless," it's a comedy set in the 70s where two airbrain, vapid girls take down the Nixon administration. It came out in about 1999, but I'm glad I never saw it then because now I have WAY more context for it.
The best thing about the movie: the casting. The FIRST scene has French Stewart as Larry King interviewing Woodward and Bernstein... played by Will Ferrell and Bruce McCullouch, bickering like children. Dan Hadeya made a pretty good Nixon and even baby Ryan Reynolds shows up.
But my big issue with the movie was: who was the audience for this movie? It was PG-13 but the younger kids wouldn't be aware of the details that the flick was parodying... maybe it was a nostalgia thing for the older audiences, I dunno. I did like the idea of taking a moment in history where people just lost faith in the world and turned it into an almost an innocent romp, that was an interesting direction to go in.
Don't know if I would watch it again, though. But it made an interesting companion piece to Clueless (though that was the superior flick).
