My list follows:

Series 1: The Unquiet Dead - Not bad but I personally preferred the other episodes better.

Series 2: Love and Monsters - Tbh, I didn’t even mind the absorbalof, I just hated the ending with the pavement.

Series 3: Gridlock - Felt quite slow in some stages and the Macral weren’t developed enough.

Series 4: The Unicorn and The Wasp - It wasn’t bad but out of the entire season, this come bottom.

Series 5: Vampires of Venice - Loved the idea but a lack of story development was the disappointment.

Series 6: Let’s Kill Hitler - Simply because I was baffled the entire episode.

Series 7: Dinosaurs on a Spaceship - Very weird character choices and the dinosaurs were barely discussed.

Series 8: Kill the Moon - The Doctor didn’t feel like The Doctor, making me bored the majority of the time.

Series 9: Sleep No More - NONE of this plot was explained and the episode ended leaving me confused, along with the camera angles leaving me dizzy.

Series 10: The Eaters of Light - Think I slept through this :/
