So far, it seems like Goran is having fun on Twitter. He's really interacting with fans and he just seems happy to have the show back. It put a smile on my face to see him enjoying the fan comments.
As for ship wars, I've seen it get very ugly with other shows. However, unless the show deliberately fans the fights (a la The 100, for example), or plays up ambiguity or a love triangle, hopefully it will be ok. I was late to join the fandom last season, but unless I've missed something the only real "fights" I've seen are on tumblr, and they're relatively mild.
Besides, who can hate Gor
