Weekend Rock Question: What's the Best Time Travel Movie?

Choose among classics like 'Back to the Future' and 'The Terminator' in our weekly poll

The teenage time travel movie Project Almanac hits theaters this weekend. It's a "found footage" film about friends who stumble upon schematics for a time machine but find out that there are horrible consequences for messing with the timeline. It's sort of a darker Back to the Future, and it comes out in the very year Marty visited in Back to the Future Part II.

Now we have a question for you: What is the greatest time travel movie ever released? Feel free to vote for a classic like The Time Machine or Planet of the Apes, a 1980s flick like The Terminator or Star Trek IV: The Voyage Home or something more recent like 12 Monkeys or Primer. If you vote for Back to the Future or any film with sequels, please specify which one you are selecting. Please only vote once and only for a single selection.
