I made it through an hour of this movie and when I saw there was 54 minutes left, I had to stop because I couldn't watch any longer. "I Want You Back" starts off as a basic rom com (one we've seen many times before, done way better) and eventually takes on elements of a crude comedy like Hot Tub Time Machine. I'm sure this one will get some bad reviews. It's a shame because I liked some of the characters and some of the dialog and scenes are quite funny. And some of the acting (particularly by Jenny Slate and Charlie Day) is quite good.
The plot is one dimensional. A man and a woman are dumped by their respective paramours, and spend the rest of the movie hatching a weird plot to get them back. In the process, they recover things about themselves that they left behind.
The movie starts off well but doesn't maintain a steady momentum and just when it seems to settle into some good scenes and writing, it then blindsides you with some truly cringe-worthy scenes and situations. There's some offensive language at times (mostly from a 12-year-old which makes it creepier), at least one sex scene that I know of (off camera but loud). And there is some Woke crap, but not as much as is typical in an Amazon movie.
On the positive side, Jenny Slate is very charming and has great comic timing - she reminds me of a younger Kyra Sedgwick. And it's also always great to see Gina Rodriguez (another one of the main characters), even if her character feels so thinly written.
Overall, it's silly fluff and rather crude at times, and there's not enough good here for me to keep going to the end. I got a few laughs out of what I saw so far and that's what I needed right now when the state of our country is so depressing. But I also know when I've had enough, and it's time to cut and run.
