Great ideas but...
Somewhere along the way it got lost. I think perhaps the improbable team up of Frank and Roxy may have started the downward spiral. Oh sure I liked them together and liked how Frank was a decent man with her (if anything she seemed to want to escalate their relationship - and even that happened too quick to be believable) but the improbability of it was hard to get past. Even in the context of a sociopolitical farce.

And not in keeping with a farce the end was terribly sad. The ancient Greeks defined the difference between Tragedy and Comedy by one factor; the protagonist living or dying. If they lived, it was a Comedy (regardless of whatever horrible things had happened to the character in the play); if they died, it was a Tragedy. Going by that, this is not at all a comedy.
I love Alice Cooper but my fav song in the film was "I'm Not Like Anyone Else". Or whatever it is called as I have never heard it before (sounded like The Kinks or Ray Davies solo).
