Not a lot to say about series eight that hasn't been said already. Capaldi hits the floor running with his portrayal. There's a good repartee with Clara despite her story having reached a climax with The Name of the Doctor. It has a reasonably subtle story arc to it that doesn't get in the way of the standalone nature of the individual episodes.
My favourites here are 'Listen' (a great meditation on fear and its sources within the subconscious mind) and 'Flatline' (Great variation on an old SF idea with some mind-blowing visuals). The worst is undoubtedly 'In the Forest of the Night' which, whilst elegant to look at, feels patronising in its storytelling - like a kids' TV show that needs to emphasise its subtext via the characters' posturing and lengthy bouts of exposition.
