I don't know why people are ranking Dark Water and Death in Heaven as different episodes since they are essentially the same story. Meh Oh well, here's my ratings:
1) Dark Water/Death in Heaven
Fantastic finale! Some fantastic imagery such as Cybermen crawling on the outside of a plane, Cybermen coming out of graves, some very deep scenes (especially when Brigadier saved Kate) and yeah, it was just brilliant. I found Missy rather annoying in part two though, she didn't rub with me well. I didn't see the point of her having a Scottish accent, why does the Doctor and the Master need to be Scottish? Plus her voice is to shrill. But other than that very good.
2) Deep Breath
A really good way to open a series, felt very Steampunk and since that's what I like, it's probably why it's so high up on my list.
3) Robot of Sherwood
Surprisingly good. I don't usually like humour in Doctor Who, but for some reason this episode sat particularly well with me.
4) Into the Dalek
Rather enjoyable!
5) The Caretaker
Also surprisingly enjoyable, and that's what matters.
6) Mummy on the Orient Express
Also surprisingly enjoyable. One of the worst and least imaginative names for an episode in any show ever but I actually liked the episode quite a bit.
7) Time Heist
An average episode. Not bad but not brilliant. Still better than most of Smith's dreadful run mind you.
8) In the Forest of the Night
Average. Rather silly, quite stupid actually. But I still enjoyed it a little.......but still really stupid.
9) Listen
I don't get why people like this one so much. It's rather boring really. For the whole thing I was just waiting for it to get started. And the whole Clara on Galifrey pissed me (and everyone else) off.
10) Flatline
Seriously, why the fuck do people like this one so much? I got some rather bad memories of Fear her and the likes from this. This whole Clara taking charge thing was silly, the Doctor in a mini TARDIS was laughable and the special effects were rather poor. A really silly episode in conclusion, I don't get why people liked it so much.
11) Kill the Moon
UGH!!!!! Kill it, kill it with fire!!! The moon is an egg, THE MOON IS AN EGG! The Doctor was a colossal dick in this, the science behind this was silly, and ugh, this was just awful. It's like it's from the very depths of the worst part of the Smith era. *stabs violently*
