This is a collection of five episodes of 'Family Guy', selected from the first few seasons by the show's creator Seth Macfarlane. If you're already a fan I'd advise not buying this since you'll probably end up buying the full boxsets anyway.
If on the other hand you're new to the show and not sure if you'll enjoy it, it's probably one to give a look. It's an extremely funny show but you should probably see some before you buy it, particularly if you tend to be easily offended, and this collection provides a representative sample of what it's like.
The show follows the often stupid adventures of an honest-we-didn't-steal-the-idea-from-the-Simpson's lower middle class American family. The show's similarity to The Simpson's is it's only real flaw, but to be honest the material here is so much more adult than it's yellow counterpart that you'll soon not care.
By the end of this brief boxset you'll either love the show or hate it. And if you love it then you've discovered a great little series with six seasons already on DVD and more on the way.
