Hadn't heard of this until 18mths ago when it was mentioned on a forum discussion about the legendary HHH.
Not a Carry On/Bless This House fan by any means, so I wasn't sure what to expect... then I seen the names Galton & Simpson stamped on, like a TradeMark of Quality Guarantee.
First series is just perfect, and another example of G&S at their finest and their most prolific. Every bit as clever, expertly detailed, well-timed, well-judged, and well-worth-it as Hancock's Half Hour and Steptoe & Son.
You can sense other characters developing as Series 1 progresses, and the last couple of episodes in particular leave you with the feeling that had it stayed G&S, with SJ and the majority of the supporting cast it really could've developed into something special and a series that would've been as significant in early-mid 60s TV history as HHH was for the mid-50s to the turn of the decade.
I've not done the reading to explain this, and websites don't say why, but it all then changes. Only 3xS02 and 2xS03 episodes survive, and my DVD is missing one but from the four that I have you just know that the writers have changed, and there's also a feeling that the budget was either slashed or Sid stuck it on trap six at Crayford! One thing that stands out is Sydney Tafler being much less effective as the S2/3 sidekick than he was in the S1 role, Sid's heartless, inhumane, and asking-for-it bookie.
But don't say no if you get the chance to see them, because even the post G&S episodes are dozens of times better than the toss that poor Tony ended up churning out on ITV a few years later.
Sid landed a good one, whereas Tony had to deliver quips that made you want to quit, and storylines weaker than a pensioner with brittle bone disease. (ATV Hancock has the wit and charm of a 2022 BBC1 sitcom, written by a woman and starring one person from each legally protected group, where each victim kicks an unemployed native Brit in the painful area!)
So, six classics that deserve a lot more attention than they've had, and four more episodes of an above-average nature.
If you see it reduced on a re-selling site, grab it.
