Fantastic.
Perhaps I'm biased because I absolutely love this type of entry but I have to say that this movie is amazing. Even if I strained I don't think there is much I could tell you to improve upon, I'm truly impressed by all aspects of this movie.
First of all, the graphics were great. You really spent some time on the shading and lighting which made the characters and scenery look fantastic. The frame by frame animation flowed very nicely, and just because it was done in that style you still didn't slack off on the detail, which is a rare thing I must say.
The sound was also perfect for this movie, the effects and music seemed to really set the mood nicely. The music was also used very well to build up parts, like for instance when the guy returns "new and improved" the music quickens and that really made it that "hair raising", "tingly" (for lack of a better word) kind of experience which really made me love that part of the movie.
The battle sequences were outstanding, and the story flowed great with its ups and downs. Even the portion where it slowed down was done perfectly, with music that matched great and with the nice "camera movement" if you will, I never once found myself bored while watching this.
You've impressed a fantastic style upon your viewers throughout this series, and this is the best one yet. When I look at all areas of what you've done I'm pleased with everything, and after watching this one I can honestly say I hope to see another entry from you soon. It was a pleasure to watch, and a pleasure to review. Great work my friend.
