I think this film has some amazing acting. As others have noted, Laurel plays himself and also his own sister. Hardy does the same. But - the women characters they portray are different to the male Laurel and Hardy. The women characters are not Laurel and Hardy "in drag". They really are playing 4 different people.
The dubbing of the women's voices is perfect, in my opinion. The women who dubbed the voices really capture the feeling of Laurel and Hardy. They are great. The syncronicity of the dubbing is awesome.
I also think the photography - scenes when the four characters are having dinner together - is great. They really create the illusion of four separate people talking and bickering.
I don't want to risk spoiling anything for anyone and so I will not describe any of the truly funny scenes featuring each of these characters.
Suffice it to say that the film is very funny.
