I bought this collection, even though I already had the first two movies in hi-def, because it was only a couple of bucks more expensive than the Blu-ray of The Dark Knight Rises and actually had extra features for that movie.I felt at the end of this movie [The Dark Knight Rises] like I did when I first heard Beethoven's Opus 131. I was so overwhelmed at the mastery of the medium that I had just witnessed that I had a hard lump in my throat, tears on the edges of my eyes and several suddenly-caught breaths. When in the realm afforded us by such greatness, we are like angels discovering we have wings. "Hey, I never knew I could fly like that! Thank you sir!"
