Because butts were hurt. They were always going to be hurt. TFA was the first one and it's just nostalgia and "Awww I remember that!" And it follows a formula. Abrahams is a great director when working with a formula. TLJ has a slightly different feel and because Fandoms believe that they should somehow have a say in the way the storyteller tells the story, they get super butthurt when something happens that they don't like. Then come the trolls, who don't give a fuck either way and fan the flames. I grew up with the first three movies and I love them but I guess I'm not enough of a FAN to get as upset as they do. The sequel trilogy is watchable. Also you could not make anymore and I'd be ok.
