I do not understand the high praise for this film.

Rating: 1/10 (2 December 2016)

I spent the whole movie waiting for something to happen. It didn't. The story was trying to be clever, but failed spectacularly. You meet aliens what's the best way to start communication? Oh yeah, write your name on a board. Then suddenly they give you the power to visit any point in your past or future? The aliens live in non linear time? They will need our help in 3000 years? Just ridiculous. At least I'll be long gone when they make the sequel in 3000 years!
The people in it are good, and give great performances, but the story is just awful, and so slow, and by the end of it you feel quite cheated and depressed.
It just goes to show how different people are when you read the reviews so many people enjoyed this giving 10/10's, but I find this inexplicable. I would have given this a 4 or 5, just for the acting, but I couldn't bring myself to do it!
As bad as Signs with Mel Gibson, so if you liked that, then this will be a treat.
