Buffy vs. Edward Remix Unfairly Removed by Lionsgate
Doesn't look like fair-use to me.The rebelliouspixels version, with its extensive on-screen critique is fair-use since it appears to be a critique.  But if the original YouTube version lacked that, then the video devolves into little more than a fanfic video by a Buffy-loving Twilight-hater.Even the rebelliouspixels version appears to contain far more "quoting" of the original material than is needed for its critique.
