I am hardly a fan of national film critics, but they are right on the money with this one - it stinks.
One major objection is having David Janssen playing the gangster Arnold Rothstein. What kind of casting is that? He couldn't be less credible in that role. Other cast members don't fit in here, either. The whole thing is a mess.
The first half hour of this movie doesn't exactly grab your attention, but when the romance sets in, it really puts you to sleep....and really never recovers. "King of the Roaring Twenties" sounds like an interesting, exciting gangster film but is just the opposite. Don't waste your time.
