The perception of this movie
I think a problem I had with this, and certainly a lot of other people did, was the perception of what was to be expected. It is marketed as a thriller, so thats exactly what I was expecting; something tense, edgy with suspense and fast paced. However, I don't think it's a thriller at all, more of a drama.
If you sit down to watch this as a thriller you will inevitably be disapointed. If you view it as a drama, the result is better. I think it's redeeming feature is seeing Al Pacino playing a character you wouldn't have expected him to play.
