I’m only joining in because I’m bored, but I was pretty indifferent about the series, if it was on is find myself watching it almost despite myself, it washes over you inoffensively enough, but I’ve never laughed at it (last of the summer wine was the same).
This film will be shit though, not because I don’t really like the source material, but because instead of creating a new story with new characters, they’ve used the original ones so even the biggest fans will spend the entire length of it comparing them to the originals. I wouldn’t be surprised if the story is a patch work of most popular scenes from the series.
