This comedy is ostensibly British, but directed by an American (Frank Oz, who will always be Miss Piggy to me). Also one of the Brits is played by very American Alan Tudyk, but he does a decent accent, at least to my ears.
The idea is that a family is getting together to pay last respects to its recently-deceased patriarch. But the family is a collection of neurotics, with various forms of insecurities, There is also one (1) drug dealer and one (1) very short former acquaintence of the deceased (played by Peter Dinklage, also American, but he's playing an American, so that's all right). The recipe is: put these people in confined quarters, stir, and watch frantic chaos and hilarity result.
It's not bad, but it's hard to attach to any of these silly caricatures.
