If the name Jimmy McGovern means anything to you, Banished (8.30pm, Fridays, UKTV) might seem something like manna from heaven: McGovern doesn't make much television, but when he does you tune in.
For fans, the British screenwriter is one of those rarities: a writer with a fierce political point of view who creates television that says important things, but not without a bloody ripping yarn as well.
Cracker, a drama about a boozy, sarcastic, crime solving psychologist called Fitz (played by Robbie Coltrane like his life depended on it) is his most memorable of course. But most of his work (well what I've seen of it) - The Lakes, Accused, Hillsborough - is as good as television gets.
Which is partly why Banished, a fictionalisation of the very first days of Australia's first penal colony, is just so disappointing.
