10 Perfect Movies With One Glaring Flaw

2. You Can't Kill In The Future (Unless You Can) - Looper

Looper's time-travel makes no sense. There, we said it. Making the plot-convenient time-rewriting of Back To The Future seem sensible, Rian Johnson's film features a fluid timeline where cause and effect are a little warped; if your future self is in the same time as you, removing a finger from current you suddenly removes future you's finger. But while it's utterly ridiculous, at least it follows its own set rules; once the concept's introduced it works in the same manner the whole way through. The same can't be said of The Terminator.

Not all of Looper's ideas are as consistent. The film is set primarily in the not-so-distant future where Joseph Gordon-Levitt kills people sent back from the not-so-distant-to-him future. The mechanics of why are rather basic; due to increased surveillance it's impossible to kills people in the future-future, so when the mob needs someone offed they nab then and send them back in time. OK cool, we got it. Now for ninety minutes of Joseph Gordon-Levitt turning into Bruce Willis.

Except this 'no killing in the future' rule isn't stuck to; when the hired goons come to take Bruce Willis back in time they accidentally kill his wife and cover it up by burning his house down. If that's all it takes to get away with murder why bother with a complex time-travel plot spanning thirty years?
