A fashion unconscious FBI agent goes undercover in a beauty pageant to catch a badguy. In the process, she grows to like and understand her "fellow" contestants. Nothing really highbrow going on here.
Sandra Bullock is the agent. I've really liked just about everything I've seen her in, and up to a point, this one was no exception. For being as attractive as she is, she does a very credible unattractive (or at least insecure) part. And Michael Caine was great, too, as the image guy who has to make her into a credible contestant. Oh yeah, let's not forget William "The Man" Shatner. (Or should we?) Naw, he was fun in it, too. (We have a running family gag about who the greatest actor of all time is: Shatner or Adam West? You be the judge...)
Above, I said "up to a point". That point was about 2/3rds of the way through the movie, at the point where you learn who the badguy is. It was the oddest thing: after that moment, it was like a different writer/director took over, and it became a different movie. And not that good a movie, either.
Anyway, apart from that, it was a tolerable movie, although not really one I was all that interested in seeing again.
And lately, Wife rented MCII, which I skipped. She said it wasn't worth the rental: predictable and trite, mildly amusing.
