I just watched the first three seasons back to back. Seasons 1 and 2 were absolutely superb. What a wonderful duo the Doctor and Rose were. Then came season three. What happened? Terrible writing, plotless episodes, waaaaay too much political correctness and, what's the black girl's name (seriously, she's so bland, I can't even remember).Hopefully Season 4 will be better. Because if not, Doctor Who lost me as a lifelong fan.
