Michael Craig's version from 1993 contains a lot of humor, including a reference to the dreams of crossdressers.
Any movie, even one set in a fantasy or science fiction universe like this one, has to adhere to a set of rules. You have to believe that what the characters do make sense.
This one is a bit ambiguous in this respect. It takes time before the dear doctor actually understand that he has become a woman, but when he does he does react with the expected sense of confusion -- I guess.
But it is disappointingly common in movies like this for the protagonist to give in for the first attempt at seduction. Just like that!
Still, there are some great mirror scenes here!
