Too true, that's why usually I wait, I look around for rumours.I know for sure there's a Dogma DVD 2 discs in the States, over here we still have the 1 disc. I'm not gonna buy Dogma until the 2 discs come out, but I sooooo much want that film.
I try my best to buy the films when they're two disc. The only time I've bought the same movie twice because of a better version is LOTRs, cause I wanted both the normal version and the 30 extra minutes version. But that's it, I try to stick with one DVD. If it's got what I want, that's fine by me
And, most Big Blockbusters are 2 discs, if you buy one that ain't, you really aren't that clever :p hehe. But I do know where you're coming from.
