My dad was really into Doctor Who when it first became a thing way back in the day, so I've known about it since before they came back with the new series on BBC. My fiancé is really into it, too. I enjoy it. I'm not obsessed with it, and I'm not too overly fond of some of the Scrivere during Matt Smith's run, but I like it.
Eh, it's not my thing at all, I used to have to watch it a few years back with my family when David Tennant was in it. It's never really appealed to me but my ex is obsessed with it.
