I hope it's not too late to put this on my Christmas list. All 218 episodes on 62 CD's, bonus material, a 32-page episode guide, among other things.
A few years ago, I got the entire That '70s Show series for my birthday after I had previously gotten the first two seasons separately. I was late to start watching Smallville because I was 5 when the show started. I only have the first season.
