Somehow this movie doesn't entirely work for me, but I can't decide if that's because it's too crazy or because it's not crazy enough. It's just too out there to feel like a realistic setting, but the plot is too serious to feel like an absurd satire. That said, there are a lot of great jokes. And I do love how ridiculously far both the "couples" group and the "singles" group go to make sure they're the exact opposite of the other.
One important note though, I'm very disappointed that nobody ever got turned into a lobster. You had one job, movie!
