Like the first 3 collections, this one has a great variety of episodes, and its fair share of A+ ones which are as fine as anything that has ever been shown on TV. Unlike the first 3 collections, this one has several rarely seen and/or double length episodes, and is even more of an acquired taste. Die-hard fans and collectors will want to own this set. Those exploring TZ might try one of the other 3 collections first. If you like, read my reviews of those as well.
