We're The Millers
Saw this as a double feature at a drive-in theater paired with The Conjuring. My girlfriend and I went because of The Conjuring, but We're The Millers had me laughing a decent amount, mainly just because of the main actor (name is slipping my memory right now). His sarcasm is just great IMO. Wasn't a great movie, and it's a ridiculous plot, but I wish I had seen it AFTER The Conjuring because...
The Conjuring
...I HAVE NEVER BEEN MORE SCARED OF ANYTHING IN MY LIFE. From the opening scene which didn't even really have anything to do with the plot of the movie at all, I was freaked out. It was a really cool movie. They did a nice job of building things up IMO, and while it got more and more intense as it went on, it was scary throughout.
Also, what added to the scariness was driving home afterwards. The drive-in theater is basically an empty, unlit field with dirt roads back to civilization. Not cool trying to find my way out.
