[Telepathic Intruder]

Time travel movies are inherently complex because they must to some degree deal with the impossibility of what’s known as the grandfather paradox. How is it possible to change the past in a way which completely contradicts the future? Some sci fi attempts to solve it by eliminating free choice, or by creating alternate universes. None really have, however, since I believe time travel into the past is inherently impossible. Time has no direction, just a magnitude. You can slow it down using relativistic time dilation, but not reverse it.

Looper has a hilarious take on the time travel paradoxes. The two main characters are in an all-night cafe after just meeting each other. Before the one guy can say anything, the other guy says something to the effect that if I tried to explain it to you we'd be here all night with straws pointing in all sorts of directions.

I still think that's the best way time travel was "explained" in a sci-fi movie.

Time travel movies are inherently complex

True. I thought Primer and Predestination were the most complex and confusing.

2001 was sort of poetical and mythic.

Maybe it's like the contrast between Christopher Nolan's Memento and David Lynch's Mulholland Drive.

Memento was confusing but once you got the idea it sort of "made sense." Mulholland Drive left reason and logical coherence far behind.
