one of my main complaints about grading is that you're locking the item away forever and it can never be used again. when it comes to a blu-ray set of Grease, Grease 2, and a stage adaptation my high school did in 2012...maybe there's some benefits to grading!
Why? Why must everything we enjoy be sealed up with a "grade"? I get baseball cards being put in plastic because you can still enjoy both sides of the card. But a Blu-ray?
