Inferno is quite good. I usually tolerate “alternate universe” stories as just an excuse for the actors to have some fun. But Inferno tries to make the most of that device.
I went on a binge of IIRC the first three seasons of Pertwee a while back. One thing I rarely hear remarked upon is that these stories had probably the best stunt work in all of Doctor Who. Believable fights, real falls and real crashes. Real helicopter stunts.
Another thing that stuck with me, not having seen these for like 20 years or so, is how effective Caroline John was as Liz Shaw. I was spoiled by her charisma and intelligence for those few episodes. I thought it was lame following her up with Katy Manning as Jo Grant, being a nice but relatively credulous and slow-witted companion for the Doctor to explain things to.
