They started to have six last year, right? Yeah, they already had more nominees than most awards ceremonies, at least in the acting categories, since they have them divided into drama and comedy; they didn't need to add more slots as well. In more than one category there's some nominee that doesn't seem totally worthy of a nomination. Like Moana 2 in the animation one, for example. I didn't expect it would get in, although I shouldn't have been surprised since they nominated Wish last year. I don't think this will happen at the Oscars, though, since there's one less slot there and they tend to nominate movies with better reviews.
Apparently, The Wild Robot is tied with Beauty and the Beast as the second most-nominated animated film in the history of the Golden Globes. Though, that's in part thanks to the Cinematic and Box Office Achievement category, which was introduced last year.
I haven't seen the film yet, so I can't comment on its quality, but I'm not as big a fan of Chris Sanders as most people either. I do like Lilo & Stitch and How to Train Your Dragon (the first one, which is the only one he directed), but they're not among my favorite films from Disney and Dreamworks, respectively. I've looked it up and all the animated movies he's directed have been nominated for Best Animated Feature at the Oscars, so The Wild Robot would be his fourth nomination. That might help him win too, because he feels overdue for the award by now.
