Galaxy Quest
Not a big Tim Allen fan, and I thought they would just be going for the obvious. I expected it to be for Star Trek what Spaceballs wa for Star Wars. Instead, it had a real story behind it, good acting, and was a hell of a lot of fun.
Can't Hardly Wait
I expected it to be just another teen sex comedy, and instead found it very entertaining, with characters that I could actually relate to from my own high school days.
The Parent Trap (remake)
I really enjoyed the 1960's original, and thought that updating the story would just ruin a classic. Instead, I found that it kept enough of the original story and made it work for the late 1990's, plus the adults this time were not just for comic relief but were well played and key to the storyline. Good acting all around too.
