**Spoilers contained**
I'd heard from various sources that this film was controversial and that the ending in particular was horrific. What I didn't expect was the complete change in tack with about twenty minutes to go. What starts off as a typical cowboy/indian western suddenly descends into a very dull romantic 'comedy' about Honus (Soldier Blue of the title played by Peter Strauss) and Cresta (Candice Bergen) who escape an onslaught of the cavalry by the Cheyenne. The majority of the film then focuses on these two mismatched people hence the romantic comedy bit. Donald Pleasance then turns up and abducts them both for no real apparent reason. They then escape and both turn up (separately) at the cavalry base on the eve of an attack on the Cheyenne base. As Cresta used to be married to one of the Cheyenne chiefs she escapes the cavalry base and joins up with them. So far so ordinary. Then comes the ending. After enduring well over an hour of poor acting involving a cliched will they/won't they get together storyline, the movie then transforms into over the top exploitation involving among other things a decapitation and a child being shot in the back of the head. Similarities can be drawn with the Wild Bunch at this point of the film but the Wild Bunch kept the same tone throughout and didn't resort to extreme gratuitous violence. In some ways, Soldier Blue reminds me of Frank Perry's Last Summer which also completely changed tack for a shock ending. I didn't hate Soldier Blue nor find the ending particularly disturbing but just found it to be pretty dull with an unnecessarily violent ending. If you want to see a film with a truly disturbing slaughter of the innocents, I would recommend Elem Klimov's Come and See.
