^ Don't get me wrong, I love that season. Some of those I agree are somewhat dark, particularly the one part of Deadly Assassin.
But, much of that era just has a patina of darkness over regular stories. I didn't find Talons to be any more than superficially dark. The torture in Sontaran Experiment could've been dark but it really wasn't dwelled on. Android Invasion wasn't dark at all in my book.
The Sontaran Experiment was novelized by Ian Marter, who played Harry Sullivan. The novelization expands the story a bit, and is a LOT grittier than what we saw on TV. Same with his novelization of
The Ark in Space.
And I think Wheatly may need to revisit Leela's departure. Sure Tom doesn't mope for years on end (I'm looking at you RTD) but he's clearly saddened she's gone, he just doesn't show his vulnerability to her, he shows in inside the Tardis after he's closed the door.
I choose to interpret the Doctor's laugh in two ways:
First, Leela had just asked K-9 if the Doctor would be all right. The Doctor was grinning because he already had another K-9 ready to plug in and go.
Second, I'm imagining the Doctor's gleeful thoughts at how Leela would soon whip those soft, cowardly, weak Time Lords into shape!
Classic Who wasn't like that at all. I think of it as the age of innocence where the Doctor was basically just an eccentric, slightly crazy guy travelling around, stumbling into new adventures.
So, "darker, more like Classic Who" sounds quite contradictory to me.
There were a lot of dark, or at least dark-themed stories in the Fifth Doctor era. It was even moreso with the Sixth Doctor. Remember, until the end of Trial of a Timelord, we thought Peri was DEAD - her mind and spirit completely gone, her body stolen and then killed to get rid of the alien that did that to her.
Honestly, the lightest moment I can think of with the Sixth Doctor was when Mel was forcing him to drink carrot juice and work out on an exercise bike.
For the Seventh Doctor, I see nobody's mentioned all the death and violence in
Paradise Towers? Not to mention the cannibalism that went on offscreen...
Ther seventh Doctor did trick Davros into using the Hand of Omega and thusly destroyed the entire Skaro solar system, the fourth Doctor did use a Dalek to destroy the incubator room with the new Daleks.
The Fourth Doctor did not destroy the new Daleks. He almost did, but had a talk with his own conscience about whether or not he had the right to commit genocide; he decided he didn't.
After all the new show has never outright killed a companion yet (without coming back one way or the other).
Rory and Amy didn't come back from the Weeping Angels (so to speak), and the Doctor sure acted as though they were dead...
Old Doctor Who was definitely more violent than the new one, but I don't know if darker is the right word for that.
Well, there was a lot of shooting going on (mostly in the U.N.I.T. stories), the Third Doctor knew martial arts, the Fifth Doctor shot a Cyberman point-blank and rubbed Adric's gold-trimmed Badge of Mathematical Excellence into the Cyberman's breathing apparatus to make sure it was dead (why didn't the new series ever acknowledge that the Cybermen are deathly allergic to gold?)...
Could we count all the people the Master shrunk as violence?
Why not, since they ended up dead?
Let's see, there was the traffic cop, Auntie Vanessa (Tegan's aunt), and a bunch of people on Logopolis... not sure who else got shrunk, but the Master was responsible for Kamelion's death (an often-forgotten Companion of the Fifth Doctor, only really seen in
The King's Demons and
Planet of Fire).
