Absolutely awful in the sound department.
Laughable music and terrible, annoying sound effects.
Enjoyable movie otherwise. Would've been better without the first 30 minutes. As much as I love ninja, their introduction scenes felt insanely stupid. It was like a promotional video for a video game or some crap.
