"Twelve Monkey's" was brilliant. The recent movie "Loopers" shouldn't be ignored just because it is recent. It was excellent.

"Primer" is considered by many to be the best ever made, but we are talking about movies and I can't ignore the shabby production values and weak acting in that one.

I had to refresh my memory on "The Lake House" I'd have to kinda call "chick flick" on that one. It was pretty good but for me it was obviously forgettable.

Having referred to a list, some other I have seen that deserve mention:

"Back To The Future", franchise
"Terminator", franchise
"Butterfly Effect"
"The Time Machine" They have yet to do justice to H.G.'s masterpiece.

The Outer Limits TV series had some of the best time travel stuff on TV or films. It was better than most of the movies available.
