If we are getting into Star Trek time travel, they do it at least half a dozen times and are inconsistent in the rules, (at least 3 different rules).
Wrong, with time travel, I could go back and kill Anakin as he shoots out the 'ole cooter, destroying the entire Star Wars timeline.
That's my type of time travel. It's also one of the movies that I'll stop and watch regardless of where it's at in the plot
