Not sure what it says for unreconstructed hard-man cop Gene Hunt that David Cameron adopted his persona during the election campaign.
Maybe that he's not the Philistine we'd all had him down as (Hunt, not the PM). Certainly Keeley Hawes as DI Alex Drake has had a softening impact on the man. But has it made the series better than its predecessor Life on Mars? In short, despite some fine acting, no. Especially with a summing-up finale that'll make you howl.
