TV

Gavin & Stacey
3x03 Episode 3
[Watch it (again) on iPlayer.]

Merlin
2x07 The Witchfinder
Finally picking up on this again, with just two weeks before it's all deleted from iPlayer. Oops.
Very good episode, though, with Charles Dance making a thoroughly evil villain.
[Watch it (again) on iPlayer.]

Misfits
1x04 Episode Four
Misfits does the natural time travel episode -- what happens if you change the past? -- though with its own drug-addled spin. Shame that it pushes coincidence to the max by having every major character in the same location months before they all met. That aside, however, it was a well executed episode.
[Watch it (again) on 4oD.]

Wallander [Swedish]
1x05 Afrikanen (aka The African)
A relatively weak edition, I thought, particularly at the convenient and improbable climax (would the police really send one person to a potentially-dangerous location while three went to another?)
