It took me a while to get used to the disney-like artstyle with tons of blood.
The movie is very hasty and moves on very fast barely having any pacing. There is also some awkward editing sometimes. Especially the first half of it. With a length of 75 mins this just feels to short.
The plot is alright and could have been the base for a really awesome movie but this is more like a third-party TV special.
It's not horrible. It's very mediocre. It has a few good moments but in the end they didn't use the source material to its full potential at all.
If you are interested in watching it then give it a shot but don't expect much.
