I have not watched too many yet, but " How to train your dragon" was great. It was soo good that even though I was just viewing a small amounts of each movie I was testing, that when I started viewing HTTYD, I wound up watching the whole Movie:D
Darker grainier movies are not as good, as a mater of fact if you do use for that type you will have to lower the level of , or even turn off the Darbee for those.
I works great for animation or well done live action. As was said in many posts. the better the material the more powerful the effect..
