When you set out to make a character annoying, you need to make sure that they aren't so annoying that it becomes tiresome to watch. The writers for "Someone Marry Barry" did not achieve this.
I can understand crude comedy. I have laughed at plenty of fart jokes in my time. But Barry and Mel play characters so who are so annoying and unnecessarily crude that it just becomes hard to watch. I found myself cringing way more often than I was laughing, and not the funny "Office" or "Curb Your Enthusiasm" cringing, but more cringing at how bad the writing is or how flat the jokes are landing.
I'm giving it a 3 just because the actors do seem to genuinely be trying to salvage something from this film. I like Labine, Wayans Jr., and Middleditch. And Amanda Lund had us chuckling a couple of times, but the writing was just so poor that none of the charisma from the actors helped.
It might just not be my kind of comedy, or maybe I was just in the mood for something a little smarter. Or... no, this movie just kind of sucked. Trying to shock you with dirty words, or scenes that are not funny but just ridiculous on paper do not constitute good writing or good comedy.
