This is why I can't really get interested the show these days. For years on the show we've had the same "type" of contestant (young, white, inoffensive, dull) coming on and singing Mariah, Whitney and Ed Sheeran songs every year and the one time we actually get someone with a bit of attitude and personality and the ability to sing, dance AND rap with modern song choices they're booted out after only four weeks.
I mean, just off the top of my head we've had contestants like Che such as Matt, Ben, Joe, Leon, James, Craig, Aiden, Nicholas and Christopher Maloney - all boring and all sang the exact same type of songs as eachother. Are any of them stars? No.
Mason might be annoying or cocky and might not have the best voice in the show (but does Nick Jonas, Justin Bieber, Chris Brown, Drake, Usher etc?) but he's at least a bit edgy and sings music that is relevant and commercial.
