The combination of CGI, animation, stop motion and live action does NOT work. If the CGI had been believable it might have seemed less of a chore, but thats not the main issue with this film.
The script and the directing are the major faults. Most of the time there is no dialog, but long dreary dimwitted monologues. All the while the same sleep-inducing music is being played. There is only a few minutes in the entire film without music. This is completely inappropriate.
The action is poorly directed, most of the time its impossible to follow the combatants and have any notion of whats up and down.
The story was pretentious drivel not worthy of mentioning, with a ridiculous amount of leaping plot holes.
All these things combined made me lose interest which made it feel even longer. The last hour or so of the film I just wanted it to end so I could go home.
I am still waiting for the first live-action anime that works. Avalon was a disappointment, but this was an even greater one.
To sum it up, don't believe the hype.
