I thought that Sum 41 would come out with at least a decent CD, but man I was sooo wrong. The CD was no fun! It was alot of boring slow songs. Sometimes those are nice if there is something to them... sadly there wasn't. The faster songs they had weren't even that original. They were the same old anthems that the pop-rock bands have been playing for years. C'mon Sum you had a really good CD last time! Please don't let me down again!
