Just saw it...thought it was alright. Nothing original, nothing special, but worth a watch.
Quite funny in places...some brilliant acting (Blanchett, Coogan and Molina), some shocking acting (the White chick is fucking awful, ditto Iggy Pop) but on the whole, well put together and darkly poignant. If you enjoy absurdist theater you'll probably get a little more out of this...the influences from (esp.) Beckett/Ionesco/Pinter are very apparent (in both style and content.)
