Watch FMovies. Why Not is hypnotic, compulsive and claustrophobic. It is bathed in a cold, pervasive eroticism, which, oblique and displaced at first, finally becomes explicit in one of the most bizarre masturbation sequences ever filmed. For almost two hours, we observe a young, strikingly pretty girl, nude most of the time and alone in an apartment, engaged in a sonambulistic and sensuous attempt at coming to terms with herself.
