The first is Baby by JB which has 9.7m dislikes. YT Rewind 2018 has 5.3m but unlike Baby YT Rewinds dislikes vastly out number the likes.
Imo 2012-2015 rewinds were good. 2016 was good besides the part where they had the rock. 2017 was a step down from previous years but i did like how they included way more youtubers. 2018 is just terrible. They really did not focus on many big things that happened on youtube this year and it's obvious the amount of people involved decreased by a lot. I did like how they showed more lvoe to animators though.
