Underrated!!! There are many reasons why people didn't like the film, craziness, too much music, bad acting but the problem when people when they saw this they didn't think families can act like this but Larry must have based it off of life because it happens! My family too broke up over money and principle (though we screamed more than this movie has), until recently we hadn't talked and wound up meeting on a funny way and solved our differences. This gave me a laugh when I saw the similarities. This movie has a good width and length.
Another complaint was the music which runs on for a bit but is really catchy and get's you in the mood of an opera.
If you like Steven Webber from Wings you'll get this as well as Craig Bierko who was up for Chandler in Friends(which is also spoofed here.)
Overall, a funny movie for David fans, though some will differ. Also look out for Larry David in a few cameos.
