A homesteader's family are wiped out by a renegade Injun party and he vows his revenge
" Wow Theo . That sounds like so many other dire generic Westerns . Tell us why you gave it seven out of ten "
Easily explained . It's an old fashioned premise done in the New Hollywood style . Hollywood had done way with the dichotomy of good and bad and decided to paint everything in grey . Some people have mentioned both THE WILD BUNCH and THE DIRTY DOZEN in their comments and you can see some very obvious parallels as the protagonist hires some cut throat prisoners as a posse and you're left with a feeling this might simply backfire on him
Another aspect is the rather bloodthirsty element . New Hollywood had torn up the Hays Code rulebook and consigned it to history a few years earlier and THE WILD BUNCH was responsible for this more than any other film and whilst it doesn't have the same directorial style as Peckinpah would have brought to the movie it's enjoyably mean enough to appeal to audience members who aren't keen on the genre
