Query: Boring Grade B western with uncomfortable cast.

Despite Mr. Maltin's high opinion, this is definitely a Grade B western, despite Claire Trevor's attempts to act as if it weren't. Albert Dekker is a boring Bat Masterson and Barry Sullivan his befuddled rival. Girlfriend shared - Trevor - tries to get Bat to give up his guns for journalism. Inexplicable Oscar nom for a mediocre score. Avoid this one unless you have insomnia.
