"Stop blaming the writers!!!"
THEN WHOSE//???? RESPONSIBILITY???? IS IT????
Depending on the context, (because you could be talking about a couple different things) its probably the Director’s responsibility. Maybe even the DP, Producer, Editor, or even the actor’s responsibility, but usually it is the Director’s job to make sure all the other guys dont mess up.
Granted, the Director is also somewhat bound by the script, but the Director is still supposed to read the script before he/she agrees to make the thing. So its still kinda the Director’s responsibility.
