Again, this is off the top of my head, so I may be forgetting something good. As before, no particular order of preference beyond the first pick:

A Few Good Men - incredible movie. loaded with great performances.

Reservoir Dogs - Tarantino's true masterpiece. Pulp Fiction was also great but tried too hard.

The Daytrippers - one of the best slice of life films I've ever seen

Deconstructing Harry - another of Woody Allen's short list greats

Husbands and Wives - ditto

Fargo

South Park: Bigger, Longer, and Uncut - honestly, I am amazed at how good this movie is. It's sort of like when you were a kid and you bought C-3PO's cereal just because of the Star Wars tie-in, but it turned out the cereal was really, really good.

Sneakers - great cast, great story

Swingers - I admit it -  the "Rat Pack" jargon doesn't hold up so well over the years, but it's still a fantastic movie. Vince Vaughn was never better.

The Spanish Prisoner - a wonderful homage to suspense films of the 1950's - in color!

Dances With Wolves

Apollo 13

The Shawshank Redemption

Unforgiven

Mrs. Doubtfire

Groundhog Day

Star Trek - Generations

The X Files
