Saw it. And, yes, I was reminded of the Nightmare before Christmas, with this film.
It is dark...Gothic.
The attention to sound is amazing. All of the little clicks, claps, twists, smacks, whips, cracks. It's delicious to the ears, if you play close attention to the sound.
Story as alright, felt a tad generic. It rang so loudly of "The Matrix" that it was almost absurd. Things such as "the machines rose up against man" and "we must go to the source". Yes, I'm dead serious.
Character development also felt a tad lacking. Very generic personalities.
Good film, though. Nothing spectacular. 6.5 to 7 out of 10.
