I don't love Blink as much as others tend to, but I do *like* it.
I'm not really a fan of Earthshock at all, tbh - the story just doesn't hold up to any scrutiny at all IMO. It's a great ride the first time around (which is what counts, to be fair), but to me it just doesn't hold up to repeat viewings.
I also think that The Five Doctors is a bit of a mess, I'm afraid, although that may be a bit of a churlish thing for me to say. It was meant as a celebration, and as that it certainly succeeds, but as a story... less so, for me at least. I always find it telling that for all the cameos, returning monsters etc., the first thing that people always think of in the stoy is the Raston Warrior Robot, the sole element not from the show's past.
But horses for courses and all that - I always say that the greatest thing about Who is how varied it is, and how there's something that everyone will enjoy - hell, there's probably a (sick, twisted and downright wrong) person out there who has Fear Her as their favourite episode, haha.
