Hello folks. I'm looking at buying Crank 2. It is available from iTunes for $20 in HD format and $25 in Blu ray from Best Buy (Amazon $20 bluray sold out). I'm viewing my movies on a 1080p 40" Sony Bravia set. How would you compare the two pictures (HD Download vs BR)? Is it going to be a big difference? I have plenty of blu rays which look great, but I haven't downloaded any HD movies from iTunes yet.
