How others will see it. You like action movies that pit good guys against bad guys? Sure you do. At least, most everyone does. Although this category of film is usually best when it's not so clear who the good guys are, as in Unforgiven (1992).
If you like tough guy action movies, and you probably do, you'll enjoy this gritty adventure, especially the scene where the good cop finally corners a key bad guy and has a brutal fight with him. The punches! The kicks! The slams! It's so exciting. I might just have to watch it again, even though I know who wins.
And there are three unexpected plot twists along the way. Don't expect me to keep them a secret, however, since it is necessary for me to reveal them in order to ridicule them. Sorry about that.
How I felt about it. It's all a bit over the top. The characters, especially, but also the action and events. Our hero is raspy voiced, incorruptible, adrenaline enhanced, and humor impaired McGraw, who will born a cop and will die one, simply because he can't imagine another identity.
The target is contemptible Marie Windsor, a compassionless and selfish cynic. Is it all just an act? But if she's a police woman and a decoy, why play the jazz turntable which risks her life? In any event, why doesn't the cop stay in his cabin to protect the target, and get backup to look after the bad guys, who actually introduce themselves to him.
Finally, if White is the real mob wife, why would she be put on the same train as the decoy? Why would she hang out in the dining car, if she is the true target?
Finally finally, all these people on the train, and he keeps running into the same four or five people, Was the Screen Actors Guild on strike that week?
Oh, it's not a bad movie. Of course, I am too harsh on it. Enjoy the suspense, have a laugh at its expense, but don't confuse overwrought action for a gripping detective story.
