[This review is spoiler free!] TL;DR: It is a promotional music video. It's not terrible, but not life-changing either.
I decided to watch this music video because I had taken an interest in the series and figured I wanted to know what exactly I was getting myself into. Considering it is a 3 minute long video accompanied with Russian rap, there isn't much I can properly review.
It does a decent job of getting you intrigued into the show. Seeing as the MV came out before the anime, it is like being able to see a glimpse into the director's head, which is something you don't see often in today's anime community. However, the song itself anything you'd consider adding to a playlist, in my opinion. In theory, the idea of creating a music video before the anime itself is very unique and fresh, especially for 2005.
