Thank you.
So "the film's poor reviews may also be a
function of faulty casting decisions" means "poor reviews may also be the
results
of faulty casting decisions, not just of the scrip of film that may
probably have certain shortcome"? I was confused with "function".
But I don't get "casting decisions in an otherwise solid production".
Does it mean that these casting decisions did produce a good film, but
were just wrong for critics, or that "the maker/director of the
decisions is competent to make good films, but in this film s/he just
made wrong casting decisions?
Hope you will understand what I say.
