First of all, I have to say that this was an absolute bargain! Hours and hours of hilarity! As someone who has only just got into Family Guy, I found this the ideal way to do so. You can start right at the beginning, and watch through each episode at your own pace. You don't get every single episode however. The Star Wars style spin-offs and Stewie Griffin: the untold story, are just a couple of episodes that are sadly not included in this package. But you can purchase those for a few quid on here anyway, so that is not too much of a problem.
The issue I have with this is the complete mess-up of the seasons. The seasons seem to be spread across the discs (eg season 1, has all the season 1 episodes, and half of the season 2 episodes), and although it says seasons 1-11, in actual fact it only goes up to around half-way through the tenth season. Despite this mix-up, I don't think you will get as much material at such a good price anywhere else.
A definite purchase for any new or existing Family Guys fans!
