O Matador

While it could be called predominantly 'Leone-like', this brutal western has influences from all regions but still firmly sets a Brazilian tone for a new sub-genre. I say 'new' based on my not seeing an S.A. example before this. There are a few editing/story problems that may indicate a director's cut in the future, but they don't take away from the flow of the story. If you like exploring modern westerns, it's worth a look.
