SD vs HD Comparision (with pics)

[Steve 3.2]

Thanks for the link, OriGin.  Those are definitely some nice shots that show off the differences between SD and HD. 

But does HD make The Departed a better movie?  And is it worth an extra $10 to buy it?  (Amazon has the DVD version for $18 and the HD DVD one for $28 at this time.  List prices are $29 and $40 respectively.)  While HD may make it look a little prettier, I doubt the higher resolution makes all that much of a difference.  And I'm certainly not going to pay more for a movie than I have to.
