I recently finished my second viewing of Season 3*, and to my shock, it was ten times better than I remembered. I really hated the conclusion to Last of the Time Lords back when it first aired, but I absolutely loved it and appreciated it the second time around. Maybe it's just because I was expecting all the silly bits.But... with 3 there were far stronger episodes, Human Nature being one of my favorites and although the finale has a love it or hate it thing with the fans I personally enjoyed the pacing, the Master changing as much as the Doctor does by regenerating and the final scene between the two.
Hope to god there's a similar epiphany with Journey's End, because I wanted to love it, god knows I did.
*The DVD sets have been gathering dust until a few weeks ago. I have no idea why I've waited this long to watch them again.
