I'm thinking about taking advantage of Amazon.com's Warner movies and Samsung player deal, if the player ever becomes available again. Some of the movies I'm thinking about picking up I already have in their standard version. I read the reviews here and at highdefdigest, so I know they're high quality blu-ray releases, but I wasn't able to tell if it was worth repurchasing. The movies are Batman Begins, Kiss Kiss Bang Bang, V For Vendetta and Planet Earth. Thanks.

Batman Begins - Definite yes
Kiss Kiss, Bang Bang - depends on how much you like it. Personally, I wouldn't
V for Vendetta - haven't seen the movie in any version including in the theater so up to you
Planet Earth - Definite yes

I wouldn't necessarily bother with Kiss Kiss Bang Bang, but the rest are good upgrades IMO. Batman Begins and Planet Earth are especially worthwhile.

Yes on all except KKBB

Kiss Kiss Bang Bang looks fantastic, I'd upgrade.

Yes on all.

Thanks, everyone. It looks like the sale is over, but this will be useful information in case something else comes along, or I decide to upgrade later.

I really liked Kiss Kiss Bang Bang and thought it looked great, so if the BD version is noticably different from the upconverted standard version, I'll probably go ahead and get that, too.

Agreed...and it's also one of the best movies on that list IMO! (I'd tie it with Batman Begins)
