Seasons is indeed a great film. My wife got me it for Christmas.

This is someone's pirating of copyrighted material, from which they selected some parts, added some of their own editing and posted on YouTube. Bad form. Stealing is stealing. These small, niche production companies don't make enough to be able to afford this kind of stuff. Buy the video.
