My poor wallet

Barnes & Noble is having a buy 2 get 1 free sale on DVDs.

Should I, or should I not, get the first three seasons of the new Doctor Who?

I loved season 1, and I'm enjoying season 2 so far. As for season 3, I'm probably going to love Martha, but I've also been warned I'll hate what they do with her character. So. :/

On the other hand ... it's not *that* expensive, for three seasons' worth of DVDs that I'll (at least mostly) enjoy ...
