Watched Peckinpah's Straw Dogs (1971) today too. Not sure how I feel about it. At the time it might have seemed rather new, but I have 50 years of cinema built on top of the concepts in this film and now it just seemed like a derivative throwback with ambiguity over its rapes and violence in the film. The protagonist, while buckling down to move from an ineffectual and mild-mannered intellectual early in the film who can't deal with conflict, seems to swing to the opposite pole and still remain entirely clueless and insensitive towards his wife while apparently now "proving himself" in his capacity to kill or maim the group of men attacking the house.
The men themselves -- the "villains" -- don't really seem to have any purpose driving their violence either, they are just drunk self-feeding reprobates and aren't really fleshed out.... although I now know where the tittering villain cliche comes from (as there's one of them who continuously breaks into high-pitched giggles, which gets annoying fast).
I read a little about the book it is based on, and the book does not have the rapes (which in the film have some ambiguity in the woman's response, which caused a controversy) and it actually has a more complex plot where you can understand the townsmen -- while misunderstanding a situation -- think there is a threat that the protagonist is housing and that it's their job to protect the village, which they think they are doing by trying to capture and punish the supposed culprit (who actually is innocent in the book of the specific act they are concerned about, although he's guilty of similar crimes in the past). So the book has a lot of complexity in the moral threads. The film seemed stupid in comparison, in terms of how the hero is contemptible for most of the film and doesn't become any more admirable despite "embracing his machismo" by the end because he still is clueless about his wife and treats her like dirt. There was a lot of this film I either laughed at or I kind of felt REALLY uncomfortable watching (e.g., the rape sequences).
