Although it has its amusing moments, in eneral the plot does not convince.

It's funny watching the elements come together in this complicated scam. On one hand, the set-up isn't quite as complex as it seems, but there's an easy sense of fun in every exchange.

It's entirely possible that sending the audience out feeling lousy was intentional

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.
