True Blood: FOX UK, 9pm
After seven years on air, HBO's sexy, campy, vampy drama is taking its final bow tonight. The focus in the last instalment is on the tortured relationship between Bill (Stephen Moyer) and Sookie (Anna Paquin), as the terminally ill vampire asks the telepathic waitress to help him die - and simultaneously rid herself of her powers.
But there's also a shotgun wedding, a few grizzly ends and - as ever - several searing zingers from the show's finest asset: the brutal, delightful Pam (Kristin Bauer van Straten).
Under the Dome: Channel 5, 10pm

Don't try to work out how everyone's still got electricity to charge their smartphones, just go with it.
