Quantum Leap - Season 4 - excellent tv show, one of the best released in 1991. Quantum Leap - Season 4 attracted huge audience in United States. Nowadays, fresh tv series entering the streaming platforms, do not have 'something' what this tv show got. The mood is complemented by well-chosen music. The director is insanely talented guy. I needed some time after watching, to get back my mind. I couldn't find this tv series in full version in HD quality elsewhere so I decided to upload it on this site.
