Seldom does the title of a film refer so clearly to the genre, or in this case genres. Indeed, this film is a mix between Western and scifi.
There is not too much of a story, but in a Western town with much hostility among its inhabitants, spacecrafts arrive to terrorize the town. A number of townsmen and -women are kidnapped and a party sets out to find them.
A fairly typical Hollywood film unfolds with Daniel Graig and Harrison Ford as stars, the only not-so-Hollywood element is the unlikely mix of genres. This is not presented all that surprisingly though and actually they go together fairly well.
Not a great film, but entertaining.
