Yes definitely underrated as a comedy. This gem is currently re-running on one of UK Freeview (FreeSat) channels albeit at 6 AM (!). But it is well worth getting up to see or setting TiVo to record. The late - and great - John Thaw is now much better known for his role as the Police Detective Inspector Morse, a VERY serious grumpy character. A brilliant creation and characterisation with near perfect performances. But this is a rare glimpse into John pre-immortalisation as Morse - and he is equally brilliant. Fantastic dead-pan delivery of lines, beautifully acted with a very small support cast. It has been overlooked for too long and should be given more prominent re-run space.
