Honestly, don't watch this trailer. It will spoil some of the jokes in a movie that you really should just experience for yourself! The Kings of Summer is probably my favorite film I've seen this year. You're going to want to see it, it's just that good. If you don't believe me, check out the review here.
So, you ask, why am I posting a trailer and actively telling you not to watch it? Because it just gives me an excuse to write more about the movie and promote it! So please, don't watch the trailer but see it as soon as you can!
