YouTube - why *insert game, movie or cartoon you like here* sucks

I was browsing youtube and ran into a TWO FUCKING HOURS LONG video about how "Steven Universe sucks and here's why". I didn't even watch it, but like, TWO. FUCKING. HOURS. And that's just the video, I suppose the uploader spent like three to four hours recording the video and another five to edit it. All to say how no one should enjoy things he doesn't. Like, yeah, I know everyone has their opinions, but one thing is having an opinion, another thing is thinking that yours is the only one that matters and you can be as rude and cynical as you want while expressing that.
