Customer Reviews

Tom Baker is DR. Who...

For many of us, Tom Baker IS Doctor Who. These are the episodes shown by my local PBS station when I was growing up, these are the episodes that made me fall in love with the Doctor. PS. iTunes people-could you organize these classic episodes, ie. by actor playing the Doctor and by episode #?

I'm running out of space on my iPod

Not a very original idea, really, but K9! I mean c'mon! Here's where all that starts! I just have one question: Where are the Daleks? Genesis of the Daleks, link to the new series! And so many more! Bring on the Cybermen too. Also go 5-8 too. And can we have an season or two of #1?

Da Bomb!

I'll admit it, I am 34 years old and I love K-9. This is the story where K-9 gets his start and I think it is a great one. If you are a watcher of the new series of Doctor Who and was wondering where K-9 came from THIS is the story to watch!
