Doubt: 7 out of 10.
Roger Ebert used to write about his Harry Dean Stanton rule. If he knew Harry Dean Stanton was in a movie, he knew it would be worth his time. I have a similar rule, only I call my rule the Philip Seymour Hoffman rule.
As always, Philip Seymour Hoffman is good in this movie, and it's worth seeing. It's particularly interesting in light of recent evidence Pope Benny helped shield pedophiles before becoming pope.
It's one of those movies you'll think about afterwards, and that's always a good thing. What's the point of a film you can't take with you?
