Just watched it for the first time. I'd give it a 6/10. It is not a great movie, but I have definitely seen worse. I am not sure how they managed to spend $160m making it. CGI is so run of the mill these days, it is not like they much much more than any other film.
The Bad: Too many characters, disjointed story, choppy transitions, totally unbelievable romances, and some cringy dialogue.
The Good: Solid CGI, felt like Azeroth, bad ass Orcs, the actors (for B-list) all did half-way decent jobs with the material they were given
In conclusion, I would like to see them give Duncan Jones get another shot at a sequel. I just hope he would skip to a better story, maybe skip right to WC3 and the Frozen Throne.
