That was... entertaining, got me interested in the original series(Dr. Who).
Good job.
Overall:
-Solid voiceover but that moment with gray horse squealing was... hm, well, somewhat repulsive.
-Animation was good, but there's something that... I can't put my finger on in, but... Well, it's good but somehow strange.
Looking forward to the next episode(if there'll be any that is)
