If it is as half as good as the original version it will be a success!
I like William H. Macy so it will be interesting to see his take on 'Frank' who imo is a hard act to follow!
I dont know about it being quintessentially British because the basic premise of the show is of a dysfunctional family trying to get by while their drunk e-popping father fucks things up along the way. All of this is done with a huge amount of comedy thrown in and the strong sense of family will appeal to just about everyone.
I will definitely give it a look
