This week I heard it suggested that 'Filth' was a more realistic film than 'Sunshine on Leith'. Neither is terrifically realistic (is any film?) but of the two the latter undoubtedly accords more closely with the quotidian than does the former. More people have taken part in a sing-song in a pub than have had chips and cocaine for breakfast, whatever Goth romantics think. Adultery is a good deal more common than murder. There are more good soldiers than bad cops.
