Discussion Question: When is it stealing?

Very thought provoking post on BoingBoing today. Some guys that do a video series called "Everything is a Remix"(although their website appears to be a blank white page) came out with one for the original Matrix movie.

Everything Is A Remix: THE MATRIX from robgwilson.com on Vimeo.

After watching it, I couldn't help but call BS. It's not that I think The Matrix is a perfect movie, it's just that to me paying homage and referencing famous work isn't stealing. Now I know these guys aren't saying that the W brothers stole things, but that seems to be the undertone.

What do you think?
