One of the movies I've recently watched was The Omega Man, which is an old favorite of mine, I picked it up on Blu-ray recently and it scrubbed up pretty well considering it's age, the sound is nothing special just basic stereo ( I think ) and there was some dirt and scratching in places but overall it looked pretty good.
Of course this story has recently been remade as I am Legend starring Will Smith and while that version was technically very well made and has one very touching scene I find The Omega Man to be a much more enjoyable movie.
If you get the chance you should give The Omega Man a try, sure it's an old movie but I think there is a lot of fun to be had.
