LAST TANGO IN HALIFAX, ABC1, 7.30pm
IF you’re the sort of person who tunes into British drama on the ABC on Saturday night — and you know who you are — you’ll love this. It’s so cosy and middle class, it’s like being enveloped in a warm bath and sipping a nice cup of tea. It’s also very good, packing more story into an hour than most movies. The central premise— two old coots rekindle their teenage relationship on Facebook after 60 years — is nice enough, but there’s also plenty more going on, including a widow blamed for the death of her husband, ‘‘ women in comfortable shoes’’ and a slow hatchback car chase. Likely the best thing on tonight.
