The weird thing about television is that just when a show has gone from a creative peak to an absolute nadir is that it can then shock you midway through it's third season and have one of it's best episodes ever.

Spooks aka MI5, in the US on A&E, is one of my guilty pleasures. The first two seasons were completely riveting. The third started rather well, but then went limp and boring. Two of the three main actors had decided to move on and the storytelling seemed to limp along until they were disposed of, but... they're gone now. And the episode eight was right up there with the best of the first two seasons. I'll be holding my breath until next week...
