I don't mind them for what they are as at the end of the day they're not exactly trying to reach out to an older audience if they last that'll happen naturally.
However i watched their three performances on The Today Show their US premiere and they were dreadful, absoluetly cringeworthy, excrutiatingly bad and all you could see was girls screaming despite the fact they were dreadful and no personality during their interview which just made it worse. For all The Wanted's cockiness and arrogance they at least have some presence even if it is negative personality traits.
Considering the standard of singing in the US or even just boy bands they were awful, like them or not at least Backstreet Boys,NSYNC,Take That can sing live. The other thing is perhaps because they don't do the boyband dancing thing it actually exposes their lack of performance skills all five of them wandered around not knowing what to do. I also think they are really immature yes i'll admit at that age i was too but not the level they act or perhaps that's to appeal to the kids i don't know.
