For those of you on this side of the pond:
-Merlin-Apparently, the Beeb's original plan was that this, Robin Hood (Which has now finished and involved, flat out, the best/worst Eric Clapton joke EVER. Seriously.) and Doctor Who would run continuously on Saturday evenings, thus granting them ultimate dominion over the airwaves. Or something
Anyway, it's great. It completely ignores vast bloody gobbets of Mallory and every other version of the myths and I don't care cos it's too much fun. Uther is an anti-magic zealot king with a tortured past, Morgana is his ward and Merlin is given a job with Gaius, the Court Physician to try and learn how to control his abilities. It's very, very funny and in two full seasons has had to my mind one duff episode. Worth it for the Arthur/Merlin double act alone.
-Paradox. Signals from space appear to show crimes before they happen and an arrogant scientist and a dedicated female DI must try and stop them. This has two strikes against it (The premise may fall apart and the lead actress has gone on record as saying it's not science fiction. Sure, and I'm Pope Gregory the Ninth). BUT, Lizzie Mickery is behind this and she did kickass work on Messiah.
-Messiah-Hey look! A segue! Messiah is five seasons (Although the last is crap) of two, ninety minute episodes following the hunt for unusually ghastly serial killers. I recommend it here firstly because the first four seasons are out on DVD in pairs and secondly because it's worth it for Ken Stott as the crumpled lead and Michelle Forbes as his wife, who happens to be deaf. No big deal is ever made out of it, she's just deaf and their relationship is grounded, genuine and very sweet.
