It looks surprisingly terrible to be honest. They should've just made an animated movie if they're going to use greenscreen and CGI 90% of the time. That CGI is awful also, it looks even more plastic than in previous Hobbit.
It's hilarious how they went from relatively excellent looking real actors with makeups and real locations in Fellowship of the Ring, to over nine thousand crappy CGI orcs in Two Towers but still real locations and/or miniatures, to even more CGI in Return of the King (which looks kinda bad already) to absolutely shitty
everything CG and terrible makeups in Hobbits.
