Well, it's definitely different- but as you can see from the comments that follow, unless they're doing Dookie 2, it'll be hard for them to do anything different without being labeled a sell-out. Funny thing is that Bob Dylan had to deal with some of the same criticisms when he went electric- he was accused of being a sell-out, as well. And MANY individuals criticized U2's Achtung Baby when it first came out, even though that's the best CD they've ever put out. I think it's pretty good, too.
Wow, this reminds me of when all the punks were screaming sellout when Green Day left Look Out Records to sell more records. I do agree it's not their best album but I still enjoy it.
