I guess after collecting all the Seasons, I've become used to fact that their is no commentary or bonus material but I will give a 3 out of 5 stars for this reason. The show is great, but how can one of the best shows of all time have such horrible releases with no bonus material. Even the Seinfeld DVD's which are okay throw a couple of commentaries and bloopers at us. Cheers doesn't even have bloopers or interviews. For the true fan, shame on you Cheers!! However, after saying all this, I will still continue to buy them as long as the price range remains around $25 because asking any more than $30 would be crazy considering The Simpsons are $45 offering the best bonus material of all tv series released on DVD.
