Just post any AMVs you think are great with a description as to why. Some prompts: Does it summarize the essence or an aspect of a character, or series? Does the song chosen fit unexpectedly well, or is the editing above-average? Did it change your view of a character or event? Heck, did a good one redeem a song you didn't like before? Be as specific as you want.
I'll start:
This one sums up the original series and movie pretty well, using its own theme song, or at least I think so. The editing is pretty simple, just carefully timed rapid-fire snips from the source material but (I don't know if this is intentional) it mimics the Journey Into the Mind scenes in-series. It's sort of like they condensed the whole thing into a five-minute video. The original has been deleted, but a few other users re-uploaded it.
