#13 is pretty impressive considering it was immediately slandered by faux ATRL hipsters with comments along the lines of "this is trash compared to the original!!11" and 1D stans trying to look cool by hating a cover. I'm content.
So those are the only reasons that people could dislike the song?
I'm not really a fan of covers being released as singles. That's why I never really used my faves cover of Our Lips Are Sealed. I feel releasing a cover as a single is a waste of time and money.
I'm glad it was released for Red Nose Day, but it still doesn't mean the cover is any good.
