I must admit I'm a secret FP fan... there's something in the way their voices blend together during the harmonies, just fantastic.
I think they could do very well, they've proven that they can sing, now they need to prove they can entertain.
As Celine Dion said; "is there a place for them?"
So far I don't think there is, as good as they may be, they haven't worked out what their hook is, what makes them different... but I think they will get there before the end of the series. Oddly enough I think if they went the Eton Road route of being the "odd" boyband, kinda indie/glam/fun/rocky then they'd hit their niche. As much as I liked Eton Road, especially Anthony, I think FP have better singers across the whole group.
