I watched The Day of the Doctor tonight. It was really good!

I've never sat and watched an episode of Doctor Who before aside from catching a bit when flipping through channels, so this was pretty much my first experience with the show. Of course, due to its popularity and how much I saw of it here on the forums, I understood the basics. I knew Tennant came before Smith and what not so the basic concepts and time travel aspect of it didn't go over my head.

I want to get in to this show. The only thing that puts me off, honestly, is the aliens. The pink tentacle touting aliens. Is there a lot of that in the show? My main enjoyment with this movie was the Doctors interaction with each other as well as other people, so if there's plenty of that I'd consider watching more. Is alien and human interaction in the show 50/50? Or is it more one than the other?
