This could be the cheapest film ever made. The whole movie takes place in one house, which could be fine, but they never utilize the location properly. The actors are just constatly standing around, talking, making unfunny jokes, looking like they just took a bunch of sleeping pills. The cheapness is part of the problem but the main issue is that the movie is just never funny. I didn't laught even once.
In the end, you can make a cheap, bland looking movie with boring characters but only if the jokes land, and they never do.
