Review title: classic '80s sitcom Product review: Shout! Factory is really doing a great job with these sets. Really enjoy "Webster" S2 because it brings back so many memories of watching it when it first came on TV years ago. The first couple of eps in the set are a continuation from S1 which are among my favorites. These are the full and unedited eps that fans remember from the original run. These are packaged in the same type of clear plastic case as S1 was. Season 3 will be out over the summer. Let's hope Shout! puts out further sets. Remember, you are what you watch.

Review title: Needs an update Product review: Need new edition. Some chapters are obsolete. Even our professor said this in class, in fact we have to skip a chapter since it is already irrelevant to current situation
