It hurts to admit it, but it's true. He's making pretty much all the same mistakes GL did with the prequel films. There's so much CGI that everything looks very fake - more like a cartoon or a video game than a live action movie. The LOTR movies look so good overall after ~10 years because of how much they didn't use CGI, whereas this new movie already looks outdated. It's really stunning how much worse the orcs look in this movie than they did in LOTR.
The Goblin City is blatantly imitative of an amusement park ride. Characters get thrown around in the air and bridges collapse onto slides. It's absolutely ridiculous. This is obviously just a marketing ploy so they can build some theme park ride later. Jackson seems more interested in franchise marketability than artistic integrity.
I understand that The Hobbit is a children's book, but that is not an excuse for snot humor, that thing they called Radagast, and the countless other banalities. The book doesn't have any of the crude pandering to children that this movie does. It is a serious book with serious characters and events, told with an elegant simplicity that allows for children to understand and adults to appreciate as well.
Also it must be said that Azog is like Darth Maul all over again. He's the primary antagonist of the film, and yet none of heroes even know he's alive until the last 20 minutes or so. And then he's forgotten about pretty much as soon as he's dead. He really is a terrible excuse for an antagonist.
The new Hobbit movie is basically the middle-earth equivalent to Episode I.
