Probably the worst of the seven......
Just watched all seven of the movies in the series - "Doctor at Sea" is probably the worst of the seven. Might this be because JRJ doesn't portray Sir Lancelot? I think not, but that would be a tidy excuse. The absence of a plethora of nurses might be a better explanation!
The filmmakers must have realised something didn't quite gel - two years later they reunited the main players from the original "Doctor in the House" to make "Doctor at Large" - in my opinion the best of the seven.
