At the risk of being boringly predictable, I've got to go with the Daleks, but there've been some awesome creatures over the years.  My vote for the next one to bring back would be the Ice Warriors.

I was tempted to vote for several of them, but I went for The Daleks in the end.  I remember just what a wallop it was to see those pepper-pots of death for the first time, and it still holds up.

Well, she certainly needs to get away from King Yrcanos

It was wonderful seeing them all in order, and the clips really caught the personality pretty much every time.  I even felt a little nostalgic about Mel.

I've just been right through all his stories (audio at least) and it's tragic that more hasn't survived.  The Second Doctor set the pattern of being a little less aloof from his companions than his predecessor had been and there were some very strong "families" in the Tardis during his time.  A very fine series of stories.

Much as I love later Doctors, there's part of me that still regards Hartnell as the "real" Doctor.  It was a brilliant characterisation, going from grumpy, even unpleasant, to utterly charming in seconds.  Although perhaps the least comic of the Doctors, he handled humour wonderfully, and even had the Doctor's only on-screen romance till McGann.

I watched An Unearthly Child 47 years ago today (glances at the clock - technically yesterday) and again the following week, because of the power cut.  I was hooked from that point.  I lost track a bit during the 80s because of various practical difficulties in watching (though I've made up for that now) and welcomed the new version enthusiastically, as well as Torchwood and SJA.

I think this one will be going on the "completist" section of my list. 

Mm.  They did a "future Doctor" in The Next Doctor, and that didn't turn out as expected.  I don't think I'll try to second guess this one.

I like having canon too, but it's always been a bit flexible.  The Doctor's age, for instance, has varied from 450 to 749 to 900 to "thousands of years" without much rhyme or reason.  The regens too have changed quite a bit.  Originally, it was something the Tardis did when the Doctor's body got worn out, but there was no suggestion it happened after a traumatic death - in The War Games, no-one seemed to expect the War Chief to regenerate after he was shot (not that he'd have stood much chance if he did).  I believe the maximum number of regens was first set at seven, then changed to thirteen in Mawdryn Undead.

I agree that there's no reason why we can't have a Fourteenth Doctor, but there needs to be a reason for it.  Perhaps the Time War has changed things.

I definitely prefer thefifthdoctor's list to the original one, though mine (if I had one) probably wouldn't be quite the same.  I definitely prefer Romana I to II.  I'd probably include Barbara Wright and Zoe Heriot somewhere.

I suspect it doesn't mean relationship in that sense.

The Doctor should know if she did, since he was there

The Two Doctors (it wasn't actually a conscious thought, but it forms a coda to my Second Doctor marathon )

Just for clarification - his post

I know who you mean - she directed Jack to the second Glove, and then he met her when he was back in Victorian times too.  She was never really explained.

River obviously has travelled/will travel with the Doctor at some point, so she could theoretically be from any era.  We've had companions settling down in different eras before (19th to 20th century, 25th century to late bronze age, 51st to 19th-21st century etc).

My theory is that River's going to actually "kill" the Doctor for some future regeneration.

I don't think there was anything much wrong with the writing in the Krotons, just a crap monster design.  Fear Her was OK - not a classic, but certainly not one I'd be tempted to skip if I'm watching through the series.

Welcome to the forum

Yes, the Dominators/Mind Robber one was great because it actually played a vital part in both stories, making them much more joined up than the stories usually were.

The cliffhanger was a vital part of the classic series, sometimes done brilliantly, sometimes... not so brilliantly.  Let's have some thoughts about the best and the worst.

A couple of my contenders for best:

Episode 1 of The Daleks - just for sheer classicness, you can't beat that view down the eyestalk of Barbara cowering from the still-unseen menace.

Episode 1 of The Caves of Androzani - brilliantly written.  We actually see the Doctor and Peri killed, yet the solution doesn't feel remotely like cheating.  Everything's been set up, so when it's revealed it seems inevitable.

And for the worst, I give you the cliffhanger that goes from The Rescue into The Romans, with the Tardis toppling over the cliff.  Then... nothing.  We don't see any effect it has on the Doctor or his companions, there are no consequences and it has nothing whatsoever to do with the story that follows.  Huh?
