Beware of Massive Spoilers for Looper after the jump. Should we enjoy time travel movies for their entertainment value despite any plot holes that might arise, or are those pesky nitpicks enough to sink the sci-fi ship? That’s the question at the heart of a metric ton of gold-bricking discussions about Looper – a film that playfully and smartly waves away the specifics in search of a larger metaphor. But is that really okay? To step away from the heat of the conversation, I’d like to give an example from the past that falls in the sweet middle spot of that main question: the liquid metal absurdity of Terminator 2. My central problem with the time travel in that fun-as-hell film is that it doesn’t make any sense whatsoever. Granted, from the “present” that we’re watching, it all seems fine. The original plan failed, so they call in Robert Patrick to take over. But put yourself in the room when the machines sent back Arnold Schwarzenegger in the first one. They would have known instantly whether the plan worked or not, and that causes a lot of problems for the internal logic of what goes on in the sequel.
