I think the basic premise would have been more believable if this was a college comedy. If the cast and characters were all under 25, the lack of maturity and self awareness would have made sense. But to have characters in their 30s and 40s acting like scheming horny frat boys wasn't entertaining. I usually find Gina Rodriguez and Tom Ellis to be charming. Here... not so much. He came across as dull. There was little chemistry between them. Her character really didn't make a ton of sense. You are an attractive woman in NYC, if you really have to try that hard to get laid, you are doing it wrong.
I haven't seen Damon Wayans Jr. In many things, does he always act like he is sleepwalking? Maybe he just agreed to do this for the paycheck. I get that. Just wish it didn't show on screen.
