Yeah..... You're criteria don't really explain what a "good" movie is so I'll just list movies I have in HD that are "good".
3:10 to Yuma
American Pie
Australia
Back to the Future Trilogy (fairly noticeable difference, although the grain in older movies can be annoying)
Crank (not necessarily a good movie, but I think it was one of the first filmed with an actual HD camera and looks great)
Death Race
Disturbia
Eagle Eye
Get Smart
Ghost Rider
Hancock
I Am Legend
I Robot
Independence Day
Iron Man
Knocked Up
Men In Black I&II
My Best Friends Girl
Pineapple Express
Pirates Trilogy
Rush Hour Trilogy
Seven Pounds
Sex Drive
Superbad
The 40 Year Old Virgin
The Bourne Trilogy (Great movies)
The Fast & Furious Trilogy
Transporter Trilogy (Not sure if 1&2 are on blu-ray)
Yes Man
I have some other but I didn't like them all that much
