Can we please stop making movies about time traveling please?

I mean I understand if a crew of a ship or some guy ends up in the past or future by accident, fine, but there are so many paradoxes with having a time travel plotline that it's just ridiculous. Yes, I am looking at you, Terminator franchise. I mean ultimately if you can pick ANYTIME to go back in the past and you're immediately foiled why not send someone else back... WAY back to correct the mistake right away? The number of problems I could come up with is innumerable.
