I explained this to one of my friends and she asked "So what's the plot?" to which I replied, "That is the plot." That's the thing, comedies don't need all intensive plots, they just need to be funny. And Tag is downright hilarious.
There are very few comedies that are actually good. Many try, and most fail, but Tag is one of the few that actually succeed. I was in stitches so many times during this movie. I enjoyed the humor so much that I literally am already planning a second trip to see it.
There's not much more that I can tell you other than it's hilarious and definitely not a comedy you want to miss. 7/10 stars.
