I don't understand why sex should be censored in the first place... We're not in Middle Age anymore...

Big studios system is an american thing. Films are made all over the world without it, and there are no problem so yes you don't need the studio system. Actually this studio system is old and doesn't work anymore (mostly bad super heroes films, remakes, stupid comedies, etc).

Good job! Quite impressive. Your trailer's a bit long though (like many trailers).
