THE AVENGERS Blu-ray has of course much more special features than standard DVD. I expected that. Standard has Joss Whedon's commentary. But without Blu-Ray, you cannot see the Captain America deleted scenes. I call that penalizing the cheap. But I suspect the PROMETHEUS DVD will exclude even more good stuff from the standard disc.
I want HILL STREET BLUES: THE COMPLETE SERIES as well, and with no original musical deletions or substitutions. God willing Shout Factory will pick up the ball Fox dropped. ST.
ELSEWHERE also deserves a completed set.
