I have always loved old movies...especially musicals. This is an excellent production.
The messages for kids are a little iffy...alcohol use (one character gets very drunk) and gambling is a big theme throughout the movie (crap-shoot).
Technically the main characters are gang members and keep dodging the police. And one of the woman co-stars is a night club dancer/singer who does a couple somewhat questionable dance numbers.
However, the end is happy with the them all reforming their ways and getting married. : )
