Query: would be 5 stars but...

I am a huge fan of the GITS series, but when I purchased this DVD I encountered a gread deal of digital interference, leading eventually to an unplayable disk approx. 10 minutes into the film. No system is perfect, I figure, so I chalk it up to a defective copy and order a replacement. What do I find? Same problem, just 30 minutes into the film instead of 10. From what I saw, the story is great and the animation is excellent; overall, an excellent addition to the series. Thus, it would get 5 stars, but two DVDs (both purchased new) that are unplayable drops it down (even only seeing 30 minutes of it, it doesn't deserve a 1 star rating, to hell if I didn't get to see the entire movie).
