She's The Man would have been better titled as She's Another Disappointing and Predictable Chick Flick.
When Amanda Bynes was a popular actress with a stable career, I am sure even her fanbase did not appreciate this movie and only watched it for the supposed eye candy Channing Tatum.
The movie tried to emulate the plot of the great William Shakespeare's As You Like It with gender bending characters, however, I believe it was poorly executed.
I only recommend if you are drunk or cannot think straight. Take a shot every time you cringe at poor acting skills.
