Lucas really messed up with the pg-13 rating. From my perspective, they could have saved the gore from the movie and it would have helped it.
How do you figure he messed up?
I understand that you don't care for the gore, and that's fine, but when all is said and done and this movie is in the top 5 all time in terms of revenue (which it probably will be), it sort of indicates that he did quite the opposite of messing up.
Kind of like saying that Mel Gibson messed up with the gore in the Passion.
JMO.
