Started off quite clever, and about halfway through absolutely tanked. It's like they had a general idea for a movie, had a really good idea how to begin it, had a clever (close to) ending, but had ZERO idea how to connect the two. Threw some ideas around and when they couldn't make it work just said "screw it, the audience is stupid, so it doesn't matter". And why do I say "clever close to ending"? Because they had a clever end, and then took it about 5 minutes further, and just knocked off the ending of layer cake instead.
