For me, NEWS' biggest problem is that they don't have a... style(?). For example: Arashi is the fun and happy, Kanjani is the crazy, HSJ is the child-ish, SMAP is the relaxing(?), KAT-TUN is the j-rocker wannabe, TOKIO is the real band... but NEWS...? They don't have a unique thing to describle them. There aren't songs that i listen and think "Wow, it's really NEWS-ish :O".
PS: Please, don't misunderstand. I really like NEWS
