Did you think the secret recipe worked? *spoilers*
First off I watched two versions of this movie. I watched the official film (this film) and the one in Three Extremes.
The thing is I thought in the Three Extremes she looked like she really had lost years on her face, but in this one it didn't really seem like it and left it ambiguous to the viewer.
Plus in The Three Extremes had her like growing some crazy tongue or some *beep*
