Quantum Leap was one of my favorite shows in the 90's. I've watched it since the very first show on season 1. I am the type of TV buff thats likes to watch shows and movies over and over, so Quantum Leap will be added to my DVD collection as a definte keepsake. I plan to buy the other sets that I'm missing, 1, 2, 3, and 5 to add to my collection. I will be getting Season 5 next since I missed seeing any of it due to working nights and not having a VCR to tape shows to view later. So I look forward to that purchase, and I am sure after I view it I will have another rave review.
