Uuuuh, I could. I saw 1.0 on a theater screen in one of DC's museums during the Cherry Blossom Festival. A screener copy, I'll grant, but still. So either the DVD transfer was horrible for some reason, or 1.01 created problems that 1.0 didn't have.
I'm sure people on the internet have posted side by side shots and spotted all sorts of differences. At the risk of it looking like I'm saying that ignorance is bliss, though, when it comes to just sitting down and watching the movie like a normal person, I just seriously doubt that one would enjoy one version of the movie any less than another.
The movie may see 2-3 different releases in an attempt to make as much money as possible, but that doesn't mean that people should be out 20 bucks for no good reason if it can be helped. It's silly to own two nearly identical versions of the same thing. Lord knows, there's plenty out there that such an amount of cash could go to instead.
