Well, if you only watch "films" I guess that might be true.  But Amazon and Netflix have some fantastic programming, like House of Cards, Man in the High Castle, Stranger Things, Daredevil, you could go on and on.
But if  you think only foreign content is worthy, then these services aren't for you.  But I would suggest that you are limiting yourself, just as North American only audiences are limiting themselves by not being open to global programming.
