How bad is it? Dull and annoying.
Should you see it? No.
Okay: this film was made in a bit more than a week for about $15000 and looks it, but that's not the problem. The plot is about a guy who loses his girlfriend, is forced to go to a party, meets his old flame and acts reprehensibly and then apologizes. None of the characters is likeable and none of the interactions feel natural. The dialogue is over-written for the characters and not enlightening on its own. It might even be trying to be pretentious. Let's call it a student film and be done with it.
