Take the Rat Pack (an expression Sinatra hated, by the way), add some great songs, a decent story, AND Bing Crosby, and what do you get?
Well, less than you might expect-I've rated this a "7", because despite the above, Sinatra much of the time looks like he'd rather be someplace else, and Peter Falk's performance is cliche'-ridden.
The reason to see this one is Bing Crosby. He has several great songs, delivered in his inimitable style, such as "Mr. Booze". And his comedy bits, especially as a preacher to a Salvation Army-like meeting, are hilarious.
