If I don't like it, I don't like it. However, I understand that YouTube/Google is a business and are going to do what's best for their business interest. I can't blame them for that, but, again I don't have to like it. I liked the creativity of backgrounds. I like having the clickable buttons where I wanted to put them, and to look like I want them to look. I liked how you could put a large message on the left and right side of your page. To my eyes the new layout is too cluttered with tons of links of both sides, I believe it's too much white. "It looks like crap" "That's your taste..." Yes, that's my taste.
Bottom line is it doesn't matter. YouTube/Google has a right to do whatever they want with their business. So those who don't love it as much as you will adapt, just like every other time.
