I cannot believe I had not watched Dr. Who before just recently. I started watching about a month or two ago, and was instantly addicted. It is the perfect blend of comedy, science fiction, and action. The cheesy special effects are just part of the charm, and the storyline is too awesome for words.
I just finished The Last of the Time Lords on Friday (the final episode of the latest season), and I must say that The Master is officially my favorite villain of all time, with Emperor Palpatine in second. He has the bounce and humor of The Doctor, but also that evil twist. He is also too awesome for words.
So yeah, if you haven’t watched Dr. Who before, you definitely, absolutely have to watch it.
