Like most episodes in the last season, this is noticably below the usual standard of The Goodies. Instead of the over-the-top situation in "The End", The Goodies here get trapped in a common holiday hut, and the whole story feels like something that would rather happen in a more average series. They do make some gags, and it is not poor, just average, decent entertainment.
The episode is a typical low-budget episode, all done in a singe studio setting. The Goodies have proven that they can do 30 minutes first-rate entertainment of that (The End, Earthanasia, Stone Age). They just didn't do that here.
