Im kinda new to Blurays, so I dont have a lot to work from here, but to me, the Bluray didnt feel any different then a regular DVD at least for the 1st movie of the 2 pak. I havent viewed Magnum Force, but I would imagine it being similar in quality.
Im a huge Clint fan but never owned either of these movies on DVD, let alone Bluray, so Im still happy to have them in my library.
