Issa Rae and Kumail Nanjiani aren't going to win any awards; it's a rom com for now and it's better than nothing.
Chemistry is ok... the script is pretty much a joke cause a) everything is at the trailer. b) it's all the writer's fault for crappy jokes c) with a budget of 16 M, you ain't going to get the best script writers.
if "Always be my maybe" is a solid 8/10 (Keanu + soundtrack + #tbt + good jokes), this would be a 6/10.
