Wikipedia*spoilers* 

I read it last night, and I honestly don't know what to say about this sequel. It just doesn't seem to work with the original. At all. A few songs here and there are good in the soundtrack, but this thing just isn't right. Of course, I was horrified at the very idea of a sequel from the start, but I had no idea it was going to be like what it is. Wrong, just wrong.

I agree with you. I was curious about the sequel and to be honest, disappointed with the music. The ending was also not thought out well in the sense that many people will be upset and disappointed. I will probably see it though, someday...
