Trope play for a severely limited audience
Look, I get that the movie is puncturing Rom-Com tropes. It's as clear as frickin day. What it doesn't do is puncture them in an original or funny way. It reminded me a lot of Tim & Eric, wherein they think the joke is inherent to pointing out the tropes.
That's concept, not execution.
I'm a big fan of David Wain's stuff, and have been since The State. I love Wet Hot American Summer and Role Models. That's why this was so disappointing to me. I expected the premise of the plot to pay off in "beat to beat" laughs and it just didn't.
In my mind, the target audience is one educated/smart enough to get what they're doing, but still enamored with just that concept by itself. So if you're between the ages of 16 and 22, have a blast. To viewers with more experience under their belt, I don't see the appeal.
It's the cinematic equivalent of that kid in your Freshman dorm who used the term "sheeple" and idolized Bill Hicks.
