The only things that are ‘wrong’ with ‘SS-GB’ so far are people continually comparing it to ‘The Man in the High Castle’ and the fact that only two of the five episodes have aired. Mini-series are notoriously slow-moving and even I haven’t formed an opinion yet.
It took me three full episodes – half the series – of ‘War & Peace’ to determine whether or not I cared enough to watch the rest.
In case you hadn’t guessed, it’s just plain wait.
