So, because I’m not a professional, and I don’t analyze movies for a living, my rating system is entirely based on my thoughts on the film. So even a bad movie can get a high rating if it’s a fun one. The movies are rated out of 100%, and the gore is also rated out of /10. I don’t think there will be any other parameters, but if they are added later on, I’ll let you know before their used.
Now about the gore rating, some people don’t like gore, others ( myself included) love it. If your not a gorehound, then you’ll prob want to stick under 7/10 , if you really really hate it , under 5 for sure. And if your like me, you’ll be watching movies like Inside, with a solid 10.
