Mariah Carey is most famous for having the second widest range of any pop singer. Second only to Axl Rose from Guns 'N' Roses. And her Christmas special sucks.Mariah Carey waves her hands about like an amateur instead of singing from the heart. She's a superficial diva, and she looks like she's made of porcelain. Her performances of classic Christmas carols, such as Joy to the World, Silent Night, and God Rest Ye Merry Gentleman, are soulless and uninspired. She has an irritating love of praising herself, even having a parody of Siri proclaim its love for her and her music.In between the musical numbers are some lame comedy interludes about some dude dressed as Santa getting stuck in traffic on the way to the Christmas special. They're not funny. And in the end, he gets there and his costume turns out to be rubbish, so the real Santa takes over. This isn't even foreshadowed.It's a mild and undiverting piece of television. It's on Netflix, for some reason, and I don't know why anyone would watch it. I watched it because I thought it looked like trash, and it was. It's the kind of thing that will be useful to future historians so they can piece together what people were doing outside the major events of our time. Otherwise, it's just this weird thing about a singer who I didn't know was still relevant by 2015.
