Oliver Stone's "Snowden" is great entertainment and an important argument for pardon

I fail to see that as an effective analogy. Character and production are two different things.
And if one person makes lousy movies it doesn’t mean that another person makes lousy movies by association, does it?

In fairness it also doesn’t mean that that person will always make lousy movies. People do change, a lot and all the time. Stone, though, gets enough praise for what he does already and doesn’t seem like an ‘if it ain’t broke fix it anyway’ kind of man to me.
Does he to you?
