Actually I watched the film after I had seen the anime. I can't say I really liked it tho.

I really enjoyed the story and the plot twists ! This story is like a roller coaster. You think they're going to find him out and then ... BOOM ! something happens and everyone has to focus on something else.

However, I didn't like the cast and those 3D Shinigamis were really creepy. For me it's better when the story has includes supernatural to stick to anime or manga. I mean it's like trying to adapt a Disney movie into real life. Something is going to feel off and fake.
