Let me agree with the previous one star reviews saying 1. they didn't laugh once through this (I know some would say it's a dark comedy but it isn't effective as a dark comedy), 2. it's soulless, and 3. how could Rotten tomatoes give this a 97%. I've generally agreed with RT in the past but I'm beginning to think they've sold out. Spoiler alert here.. in order for this to be effective as a comedy or a drama there needed to be more development of the murder victims characters as evil dimwits so the viewer could get more satisfaction and empathize more with the protagonists murdering them.
About the best I could say about it it is that the plot was a cute idea with possibilities that failed on execution.
Note to self: Trust the user aggregate rating more than metacritic IMDb or Rotten Tomatoes.
