I would say get a movie with alot of explosions and/or cgi effects.
I've watched Spiderman on blu-ray and it is quite amazing, Non-widescreen DVD's (i.e early seasons of scrubs and entourage) look like sh!t on my tv (Bravia 40X) but ones that do support widescreen look about as good as blu-ray, certainly good enough for me to not buy blu-ray ($20 for a dvd VS $50 for a blu-ray of the same newly released movie).
