First: Amazon...stop lumping blu-ray and DVD reviews together - it's confusing and it renders many of them meaningless. Also, what's with reviews for VHS???? You can't buy them any more, and they look awful; so who cares about them? Just my opinion.
As for Robocop. I'm so glad I decided to buy this blu-ray box (despite the poor reviews). I've owned this film on VHS and twice on DVD and I can honestly say that this blu-ray is the best this film has ever looked or sounded. It's a dated movie with pretty shoddy special effects and all of that is glaringly obvious when watching this blu-ray; but if you love the film anyway that shouldn't matter to you.
Other people have listed the audio tracks, talked about quality, subtitles and the lack of extras...but what I couldn't find a reference to is which version of Robocop is in this boxset. Well, I've just finished watching it and I can assure everyone that it's the, far superior, Director's Cut on this disc.
So, if you don't care about the lack of extras this is the set to buy.
P.S. A request (or plea) to anyone who thinks about reviewing a blu-ray: Please, please, please, can you give details about picture quality, audio details, extras or your opinion on whether the blu is better than the DVD. These reviews that say "I like this film, it's good" or "I've just got my disc and watched it," mean absolutely nothing and are a waste of space.
