It was okay, nothing great, but not the worst movie ever. Kate McKinnon was great. Melissa McCarthy was Melissa McCarthy. Kristin Wiig was bad, but that was because they made her the boring voice of reason and gave her no lines to work with. Leslie Jones was also in the movie, I guess? Melissa and Kristin had no chemistry at all, which made the My Little Pony-like "Friendshiiiip" ending not work at all. I really liked the "special effects going into the black bars at the top of the screen" effect the first time, but they overused it.
Just a run-of-the-mill brainless action-comedy.
