Because the movie stunk.
Just like the others.
It was made by people who don't care,
for people who don't care.

And you forgot to mention that they cut out all of Ginny's lines!!

Actually, I felt that this one was a little better than the others.
Maybe it was just because of my lower expectations but,
on a scale of one to a hundred, I'd give it a seven (7).
The others would have gotten a two or so, maybe a three for POA.
