I liked but didn't love The Burrowers. I think a lot of people have The Searchers colored lenses on when they watch it, seeing so many scenes and gimmicks pulled directly from that earlier masterpiece. I found it a bit grating, really, but imagine that it would play easier on a second viewing.
The movie itself was good, but I thought even at 100 minutes there was stuff that could be trimmed or changed to make it a tighter movie. The scene where Callahan shows up after they leave the cavalry comes to mind, as what it brings to the movie could have been streamlined into when the four locals set out. I imagine they expected people to be like "what about Callahan?" and then be like "oh, there he is!" but it feels amateurish in execution to say the least.
The last 20 minutes or so are fucking awesome, though.
