Some of my personal favorites
1. The Princess Bride: Family friendly movie that still holds up after all these years.
2. Star Trek: The newest movie released in 2009 is what I refer to... really faithful to the original movies without trying to reinvent the whole thing.
3. Cabaret: I remembered watching this in college during a class about writing about film. Bought it at Wal-Mart recently and it's really good, but certainly a movie made more for adults than kids.
4. The Iron Giant: One of the more underappreciated films of the 1990s. You can get it pretty cheap, but it's really quite good and very much a family friendly movie.
5. The Dark Knight: The best superhero movie I've watched and it will be tough to top it.
And then there are plenty more beyond those five.
