The first one was perfection, and unfortunately Hollywood has yet to learn not to mess with perfection. I will forever respect Kristen Wiig and Annie Mumolo for turning down millions of dollars to make a sequel to BRIDESMAIDS; they understood that legacy has no price (of course, they didn't need the money after the first one made so much, which helps). I didn't find PITCH PERFECT 2 as terrible as some, I thought Hailee Steinfeld was a nice addition and Elizabeth Banks' direction kept things going. But they had no clue how to move those characters forward in any way that mattered, the humor (which was so fresh in the original) felt completely flat, and the Latinx character they added just to make some awful jokes about immigrants was plain offensive. I was willing to give the third one a chance, but the previews make it look horrendous. I don't know why anyone thought that these characters ever needed to be involved in an explosion or have a skydiving malfunction or be in any of those other nonsensical situations shown in the previews. It also looks like an exact retread of the first and second movies.
