None these days. With Sky, DVRAB, downloaRAB and the Internet if I want to watch something I can usually do it at a time that suits me.
Saying that I do like to find a few hours to sit down and watch TV away from the PC so it's usually a double bill on Sky to kill 3 or 4 hours.
The last two movies I can remember watching on terrestrial TV were both on around 5pm ish and were The Princess Bride and The Goonies.
