This is a cleaner look, but it does have its faults and hasn't gone far enough in customization. Someone users obviously do not like this new current layout and would like it changed. One way to fix this is to have options to change what kind of layout a person would like to have such as the one's in the new channel layout page (creator, blogger, etc.) These options would cater to everyone. One personal problem I have is I am subscribed to many people and my inbox is easily flooded, so I would like to have an option to delete the videos out of my  subscription box (like the old YouTube) so it won't clog the entire screen causing me to scroll down many times to find a video I haven't viewed. All in all a better solution to this new YouTube is to have more innovative options to appeal to everyone's needs subscriber or not. I hope this was some helpful constructive criticism.
