Interesting but ultimately a missed opportunity
I had never heard of this one before despite being a Bronson fan. Horror westerns were very rare at this time and this one starts out rather well. The problem all the real good action and eerie atmospheric moments are lost between rather static expository scenes of poor dialogue. The story veers off course too many time. I like the idea of two men who should be mortal enemies coming together to fight a common enemy but unfortunately the movie gets lost in their efforts to find common ground through endless dialogue and hand gestures.
I think a remake is in order for this one.
Despite looking a little fake sometimes the Buffalo looks really cool, thankfully they did not have CGI at this time.
