I think I only really liked Listen, MOTOE and Flatline. Deep Breath and Time Heist were okay and the other episodes were forgettable, mainly because of weak storylines and too many episodes seemed like lesser versions of past episodes. Here's hoping this two parter provides some redemption for the series, Capaldi deserves it for making the most of so little. The Cybermen could use a good story as well (hasn't been one since Doomsday really) even if it does look like they might be on the periphery with the main focus on Michelle Gomez's character.
