@Local-chan:
its well worth it. Personally I'd say its the UK's One Piece
woah woah woah! Lets not go that far!
I'd say it's more like the UK's answer to Star Trek… apart from in my opinion it's much more diverse.
It's probably a good idea to start with the newer series and run through all 4 of them along with the specials and if you like that DEFINATELY check out a lot of the classic stuff.
If you are stuck for where exactly to start with the classic stuff I can list some of the best ones... lets say three or four for each.
First Doctor:
An Unearthly Child
The Daleks
The Meddling Monk
Second Doctor:
The Tomb of the Cybermen
The Mind Robber
The Invasion
The War Games
Third Doctor:
Spearhead from Space
The Daemons
The Three Doctors
The Time Warrior
Fourth Doctor:
Genesis of the Daleks
The Brain of Morbius
The Keeper of Traken
Logopolis
Fifth Doctor:
Castrovalva
Earthshock
The Five Doctors
The Caves of Androzani
Sixth Doctor:
The Two Doctors
Revelation of the Daleks
The Trial of a Time Lord: The Mysterious Planet
Seventh Doctor:
Dragonfire
Battlefield
Remembrance of the Daleks
Survival
Eighth Doctor:
(The Eighth Doctor only had one onscreen appearance which was the TV Movie so really, after watching that it would be worth listening to a couple Big Finish Audio's)
Doctor Who: The Movie
ED Big Finish:
Storm Warning
Neverland
Zagreus
Memory Lane
The Girl Who Never Was
Blood of the Daleks
Human Resources
Other than that, if they arent already mentioned, both sides of every regeneration story are pretty good.
