I can't watch until tomorrow, but from what I have seen, Matt is a nice enough seeming guy who looks the part of popstar and can sing who is trying his best.
Why so harsh? Sure, great singers, one with far more range and ability, who were also marketable with star potential in his category were sent home. (and I likely have more reason to care about that than most here, and still have no issue with Matt)Sure, he is the chosen one. I'll even give you that he seems to put on a contrived image to a point. That doesn't make him "gross". Just a conventionally handsome guy with a good voice and some talent doing his best to get somewhere in life by taking an opportunity offered to him.
