We'll have to see what the new stuff is like - I started losing interest in the Series about the end of Peter Moffet (aka Davison, aka 5th Doctor) - probably more because of the tedious Companions than anything (best ep: Adric dies! YES! Couldn't have happened to a worse companion). Then too, every time I saw PM all I could think of was "Tristan Farnon with his arm shoulder-deep inside a cow". :)
The first four Doctors were the best and, by and large, all their Companions were excellent.
Vislor Turlough begs to differ. He NEVER stopped whining...
