I agree something's a bit off. They're nice and harmless so they'll draw in votes, and their voices do blend. But I agree that Charlie feels tacked--he's tried this with so many different groups, so it feels a bit artificial. The others are good but not really memorable singers either. I don't feel they're optimizing each other that well. And commercially, they're not really boybands--they have an older feel and look like they'll be into adult contemporary.
