content: I did enjoy the Heroes series, but the reason I am giving this set only one star is because of the terrible quality control. I received this set for my birthday, and was pleased until I noticed that the layers of one of the DVDs were coming apart on the inside. Returned the set to Amazon and got a new one - this time with two defective discs. Returned for a refund.Since then I have found that NBC Universal DVD sets are well-known for this shoddy quality, especially when bearing the "Made in Mexico" stamp on the cellophane. (Google it - collectors of DVD sets for old TV shows seem especially aware of this.) Apparently one or more of their Mexican facilities are not being maintained properly. This set wasn't worth the $20 my gift-giver paid, and it's definitely not worth the $45 Amazon is charging now. Be warned.
