I have to disagree with the earlier comments on this film. Having idly switched on the telly when I ought to have been doing something else, I found myself unable to switch off as Reg Varney's performance as the tragi-comic Sherry impressed me more with each scene. The combination of comedy and drama worked very well, to my taste, being written and performed with real empathy and what-not.
I particularly enjoyed the horrid owner of the caravan park where Sherry has been living and working - in one scene she has overheard Sherry's wife and her lover planning to run away together, and, rather than breaking it to Sherry in a kindly fashion, she simply tells him to move out of his two-bed caravan so that she can have it : he protests that the other caravan has only one bed, to which she replies, "Well, you'll only be needing one bed now that your wife is leaving you."
The scene where Sherry and his wife (Diana Coupland) go to tea with their son's upper-class fiancee and her parents is a classic unravelling of self-conceit under pressure, and quite painfully funny. (A very young Jane Seymour plays the part of the fiancee).
I found the ending a little anti-climactic, but on the whole "The Best Pair of Legs..." might not be the very best film of all time, but it really wasn't that bad either.
