I was watching 'Doctor Who' on BBC America last night and saw that Season 3 of 'Primeval' starts this Saturday, 16-May! Like I said earlier, while not as good the good Doctor...it's still a really fun show. It'll be perfect for some Summer UK Sci-Fi escapism and I highly suggest you give it a try.
Also saw that 'Torchwood: Children of Earth' will air in July! Going to be some good stuff to catch this Summer!
