Suspension of disbelief is only so strong. A short 100 lb out of shape woman beating up multiple large men who all have an extra 100 lbs on her is more than I can handle. Also, in today's political climate, the discerning among us will know within the first 15 minutes who the REAL protagonist of the movie is. The real plot of the movie is "women are awesome and self love and affirmation are the most important things".
Not nearly as funny as I expected, either.
