Probably not quite the list anyone's expecting, but top five...
1. Doctor Who
2. The Apprentice (UK)
3. Sherlock
4. The Chase
5. Pointless
Love a quiz. After that, it gets ambiguous - there are lots of programmes I'm catching up with, ones I watch regularly but aren't my favourites, once that are my favourites but were cancelled ages ago so are no longer relevant, wouldn't give a particularly fair overview. I've recently been watching, and loving, The Alternative Comedy Experience, but I don't love it more nor even watch it more than Life on Mars, which finished six years ago - and I like panel shows, but do they deserve placement in the top ten purely cos they're omni-present? Old school Simpsons is way more important to me, but while the show is still on air, I couldn't care less about the new stuff. Logistical nightmare! But those five are absolutely my most-watched shows over the last... certainly the last year.
