I loved this episode, again, the classic Doctor Who feeling and formula. Some monster at the beginning terrorizing people, the Doctor comes in, completely not expecting to be there, once again the TARDIS is flying him, and not him flying the TARDIS, he always ends up where he needs to be, with no control, and has to save the day.
Loved the ice warrior, and getting to see its real form, they did a good job on this one.
Loved the little bit about the Doctor tinkering with the TARDIS, and its relocation system moving it hehe. I was hoping maybe he'd also tinker with the chameleon circuit and maybe have it appear as something else in a future episode.
Looking forward to the next
