Ok that was a generalization, let me elaborate.
Watching The Proposal on BluRay is, IMO, a waste of the format. Watching something like Sleeping Beauty, or Monster's Inc, or even animation-heavy live-action movies like Transformers, is worth it. The clarity of the hand-drawn animation, being able to pause and read the text in the background from CGI movies that would be impossible to see otherwise, etc. Details that artists worked on that you would never see on a DVD. But I don't give a shit about watching RV or Twilight in 1080p.
I realize there are "normal" movies that have gorgeous cinematography, and those are the exceptions, but for the most part I feel that VFX-heavy movies are the only real reason for me to give a shit about BluRay. As one of my friends said, "I don't need to see the cracks in someone's caked-on make-up."
