As tvshowsondvd correctly reports, this is Volume 2 of the series, not Season 2. It includes the last 12 episodes of S1 and the first 9 episodes of S2. Volume 3 will include the remaining S2 episodes.
I liked the guest star "seance" in Vol. 2. The show has been shown so infrequently where I live, I even found an episode or two I dont remember seeing before.
I really enjoyed Vol. 2, my favourite episode on the set is Cousin Itt and the Vocational Counselor. I think this is also my favourite episode of the entire series so far. The cast makes this show so great, especially Astin, Jones and Cassidy. I can't wait to see Vol. 3.
