The only good story in Peter Davison's first series was Earthshock. A lot of people on DS, have mentioned that in previous years.
Then a lot of people on DS are wrong!
Baiting apart, I LOVE Kinda and there's only really Time Flight I don't get on with in this season, although Four To Doomsday drags a bit for me. Castrovalva is one of my favourite 'intro' stories, as much for the TARDIS scenes and previous Doctor channelling as anything.
Oddly enough I find Earthshock much less impressive these days. At the time I was hugely blown away - the Cybermen were my favourite monsters, and I wasn't that keen on Adric - but when I watch it now I find it good but unspectacular.
I think the Cybermen reveal / Adric's death being shock moments made it more than it is, and without the shock factor it's a lesser episode.
Ok, ok, the first episode's great. Fantastic, mysterious atmosphere. Reminds me a bit of the first episode of Terror Of The Zygons.
