Anne Rice? The witch series yes, the vampire series - eh.
"Twilight?" Can't comment, I'm afraid. Haven't read it, haven't seen it. I mean, just like the Harry Potter argument, it's good to see people on the bus or in a coffee shop with a big fat book, so I guess it's a good thing in the greater scheme of things.
Which brings me to True Blood, the TV series. In May, I was two episodes into it and not sure whether I'd be watching more. The uncertainty continued as I watched episode three, then four... I'm now on Season 2 Episode 3 and I like the series well enough to watch the next instalment, but I'm still not committed one way or the other. :-)
