Through the power of netflix I'm slowly working my way through the William Hartnell and Patrick Troughton episodes...It sucks that most of them are missing though, especially from Patrick's years.
I'm now going to bore you with the episodes I've watched.
Keys Of Marinus- It's a slow bit slightly interesting story involving a quest for keys for a machine that essentially controls people and ends crimes...several different locations are used so it's a bit of a cluster, but I enjoyed it.
The Dalek Invasion Of Earth- I'd seen the movie remake of this story before so I already knew the a basic plot. My main interest in this was seeing Susan's exit from the show.
Tomb of the Cyberman- My first real Patrick Troughton story. The 60's cybermen look so ridiculas compared to the newest versions,lol. It was a pretty interesting episode though.
Wheel in space-only episodes 3 and 6 exist for this story, so it was kind of confusing...another cybermen story.
So I watched the Christmas Special last night, which was okay...although I was puzzled at how the Doctor didn't seem to care about changing time, breaking several rules,lol.
Currently I'm watching The War Machines...the only story available from season 3. Started slow but it's quite interesting. Basically it's about an A.I that becomes homicidal...a bit like skynet, but better! It can hypnotise humans, and builds war machines that can jam any human guns in the area somehow,lol.
Yeah I watched the Dr Who special. It got a bit better towards the end but overall I wasn't that impressed. I'm used to Dr Who disappointing me though, so wasn't too big a deal. I agree with your observation about him going back in time without a 2nd thought. I found that a bit odd too. I also don't get why he left his two companions on that ship which was about to crash. Rather odd. Anwyays he could easily have rescued the entire crew in the Tardis, so it all seemed rather pointless.
The Invasion - Too be honest, this one is kinda boring, and way too long (8 episodes). Although because two of the episodes were missing, they used the original audio over some animation, which way pretty cool. Also, the Brigider is in this one.
The War Games- Patrick's last serial. Was actually pretty cool, although it's a bit long at 10 episodes, 8 would have been enough. First time where we find out that the Doctor's race are called the Time Lords.
