Jimmm, it's interesting to hear you feel Tom Baker's 7th season was "worse" than his 6th. The 6th has caught a lot of hell over the years, both for its "excessive" humor and its visibily decreased budget. Despite both of those, the entire season (barring that annoying Dalek story) has continued to grow on me over the years. I note that just about every story has ONE actor whose performance suggests they thought they were doing the Adam West BATMAN or something (not that that show couldn't EASILY have been much better with the right attitude in charge). Note the scientist in CITY OF DEATH with the exagerated accent (same actor who played Charlie The Bartender in THE GUNFIGHTERS-- no kidding!), or the guy who played "Tryst" in NIGHTMARE OF EDEN, who goes thru the entire story impersonating Peter Sellers' character from WHAT'S NEW PUSSYCAT.
Too many science-fiction fans insist that their "SF!!!!" be taken "seriously!!!" all the time, which can get boring, or depressing. JNT & Christopher Bidmead (season 7) went way, way too far the other way, discarding or destroying many things that made the show watchable in the first place. It's difficult enough in England to hold onto actors on any TV series when they keep wanting to move on to the next job, but to deliberately KICK a character who really works and is really popular off a show (Romana, K-9) is practically creative suicide. (Everything they did just "inspired" Tom Baker to quit, too...)
Ironically, the story that caught hell when it first aired, "MEGLOS", in the long run, I found the most fun to watch. It's got a few gaping plot holes in it... but that's an entirely different problem!
For the most part, in the right state of mind, most of Baker's last season does remain at least watchable... UNTIL I get to LOGOPOLIS. Early-on, I was captivated by this, for the most part, I think, because it broke so many "rules", because I had so much trouble figuring out what the HELL was going on, etc. But in the long run... it's where the REALLY BAD writing on the show started. Christopher Bidmead over-worked himself that whole year re-writing everyone else's scripts to bring them in line with his own narrow view of how the show should go, but the final story was a LAST-MINUTE replacement, and it really shows just how rushed he was trying to get the thing out.
In addition, once JNT decided to boot Lalla Ward off the show, and then found out Tom Baker was leaving, he strongly considered bringing back an earlier companion, at least for a few stories, to help "bridge" the transition from the show's longest-running and most popular star to whoever he wound up with. Both Lis Sladen & Louise Jameson were contacted. I believe one was unavailable, and the other turned it down (allegedly) for not being asked first (which sounds childish, so I question the truth of it). Try watching LOGOPOLIS and imagining how it might have gone with Sarah or Leela INSTEAD of that awful, annoying B**** Tegan.
The last time I watchged my entire DOCTOR WHO collection, ALMOST every girl on the show I found myself liking more than I ever had before, except 2 of them. Sarah, for whatever reason, who'd been my favorite since 1979, I had no reaction to at all this last time around. Very strange. (Maybe my taste in women is changing?) Tegan-- I just can't stand. The one bit with Tegan I enjoy is in FRONTIOS, where the Doctor tries to save her life by pretending she's a robot. "I got this one CHEAP because the walk's not right, and of course there's the accent..." That's the REAL Doctor finally showing through, after 2-1/2 years of him being buried under "too nice and wimpy".
If you'd like to see Peter Davison the way I feel he SHOULD have played The Doctor, watch CAMPION. He's brilliant on that, in every scene. He still managed to be a "nice guy", but unlike his Doctor, Albert doesn't take C*** from anyone! (Including his butler, played by Brian "impenetrable accent" Glover.)
