I don't tend to watch it now - as I still feel the earliest ( Paul Abbot written ones ) where the best ; being as they were based directly on his own experience. As has been mentioned, it does not seem to work as well for me as an ongoing comedy / drama. It would have remained a classic if left after one series like 'Boys From The Blackstuff'.
Still, kudos for it being a revelation of 'real life' for anybody living outside that reality. :)
