The Brady Bunch Movie, which I had seen when it first came out in 1995. Back then it was hilarious and it still holds up. It lacked the pow of freshness it had back then --- the surprise of the brilliant satire, but still is very good.
Amazingly they captured how creepy The Brady Bunch was. Although we watched it over and over and over as kids, we were unaware of how odd and campy it was. The creators and the actors of the movie nailed it, spot on.
I had many favorites, but the things that tickled me the most was Cindy, and the parents' dorky banter.
