Generally a strong cast, although there are exceptions, they guy from Game of Thrones is a stand-out for charisma vaccuum, but you've got Timothy Spall, Benedict Wong, Bryan Cranston etcetera etcetera - in fact, there's pretty much every reason for this to be good, with excellent source material and an excellent cast. I suspect as this was a co-production by Channel 4 (UK) and Amazon (fronting the monies) that this was used as some kind of testing ground for directors to have an episode each. The problem is that none of them are good. Passable, sure, but not good and certainly not great...
