I'd give this a resounding, and low toned "meh." at best. I hear great things about Berserk. The few episodes I've seen of the anime are wonderful, and I plan to watch the rest and even started buying the manga. I had quite high hopes for this movie, since the rest has been great. That may contribute to why I was let down. This movie is frankly crap, and if you like Berserk, do yourself a favor and skip this in particular.
The character development is rushed, and poorly explained at best. Guts feels very shallow, and Griffith is even more shallow. The story line would be okay if they dove into more parts. The intro, before we know much about Guts here, is awesome. And it's all downhill from there. The pacing is off. I felt *obligated* to like this and watch it the rest of the way, but I regret that decision now.
