On a less joyful tip, ABC has axed Invasion. Despite being scheduled right after Lost, Invasion saw US ratings drop from 17m to 9m over its first season. Shucks, that's only one and a half times the entire population of London. As is always the case with these things, there's an online petition doing the rounds, and new network The CW may help save the show. But as things stand, the final episode airs over here on Sunday 28 May. Meanwhile...
