I've often thought that the genre mix of comedy - thriller is the most difficult to bring off. Somehow the two different kinds of reality, in their extremes, don't mix easily, unless the very nature of the narrative demands it, as in Dr Strangelove.

The comic first half is somewhat slow, and deals with the infiltration of a wealthy but naïve family, by a streetwise poor one. However, when the action develops along more serious lines in the second half, the atmosphere created in the first half still carries a surreal edge, and so I couldn't believe in the subsequent action sufficiently to be thrilled or horrified.

A brave attempt, but in the end I was left feeling a bit numb. It all seemed to lack any solid centre, with serious themes looking trivial, and comic themes looking disturbing rather than entertaining. All a bit tasteless, really.
