I watched Wyatt's Watchdogs when it first came out in 1988 (I think) and thought it was a reasonable sitcom at the time. Back then there were still many 'average' sitcoms made and this is certainly one of them.
I watched the first clip on You Tube, and it seemed ok and as I remembered it. By no means groundbreaking but watchablew enough, and good to see the talents of Brian Wilde and Trevor Bannister in something different. Will watch the other clips soon.
Also on You Tube is a complete episode of Hancock (the ITV version of the sitcom) guest starring Brian Wilde which is worth watching.
