I am very sad that heroes is no more, however that is no excuse not to pick up season 4 on DVD. If you have not bought any of the other seasons of heroes you should at least buy this because this arguably is the best season of heroes, the cast has never been better, and there are some new faces that did an amazing job. Just like the previous DVD releases, season 4 is loaded with bonus features that will entertain for hours. I got too give it to the folks that created these DVDs because they clearly put a pile of work into all of them. So If you are a fan of the show, or an epic science fiction story, you owe it to yourself to pick up not only this season, but all the seasons of heroes because it is a fantastic show, and it will be one that you will go back to view again and again. in my opinion this show ranks up there with the best, and should not be missed.
