Who was the worst actor in this film?

Nobody in the film gave a flawless performance, except maybe James Franco. Ashley Benson was the only great one out of the four girls but even she couldn't be natural all the time. Rachel Korine was okay, nothing really stood out. Selena Gomez can cry and act sweet really well (since she's Disney and all) but the rest of her acting was pretty awkward. Looking serious and muttering seems to be her go-to method when she's uncomfortable. She clearly has the potential to be an amazing actress, though.

I think Vanessa Hudgens was the worst by far. She is such a terrible actress that it was almost distracting, throughout the entire film I just saw an actress trying to play a semi-psychotic badass. The only thing she can do decently is talk in a baby voice and act like a dumbass, but she does that in interviews, too. I just couldn't buy her performance at all.

This is all just my opinion, of course. Did anybody else have a different take?
