Jandy Hardesty’s review published on Letterboxd:
If there's one thing that Celeste and Jesse Forever proves, it's that Rashida Jones is a force to be reckoned with, both as a writer and an actress. There are elements of this break-up story that didn't entirely work for me, as it meanders around Celeste and Jesse trying to get divorced but hang on to each other at the same time, but the script (by Jones and Will McCormack) hits enough goofy comedy and emotional truths to make it worthwhile, and the chemistry between Jones and Samberg is perfect for the film.
