Why do you hate BBC America?
For one thing, this marathon is awesome for casual viewers who may have just gotten into Doctor Who. We should be congratulating them. I actually think BBCA has some of the best programs on TV right now. They play Being Human, Robin Hood, Torchwood and Doctor Who. Tonight I got to see a bunch of Christmas episodes of britcoms I'd never seen (and AYBS, an old favorite.) I have to say I really enjoy it.
Anyway - Waters of Mars achieved a record for BBCA! 1.1 Million viewers! That bodes well for the End of Time, which they air a promo for every other minute. Its so much better to have it on a cable channel that really makes a bit deal of Doctor Who versus Syfy.
