I don't know if they deserve the crap they get, yes they made a bad movie, two actually and they do seem to have preferences but originally they were going to try to do Requiem in space before that was shot down, they also had a reduced budget. And lets be honest, they didn't write the script (As far as I know). There might have also been some interference as well.
Although, I remember someone on set, either the brothers or someone else telling another crew member to "shut the f*** up" when they mentioned the lack of lighting.
