I saw the trailer. That was enough.
The entire movie is completely unnecessary. If you do see it, please tell me if there is a shot of that guy wearing a cowboy hat squeezing the artieries of the guy that got his legs blown off. That dude was a hero is the truest sense of the word.
I am betting you'll come back with a 5 out of 10 rating. Maybe 6 if you're lucky.
Lastly, if you haven't seen Arrival yet, take your kids to see that instead. Please.
