Starting off, I love how the MV's environment is integrated into the song, the back-alley's apparent abundance of metal clanky things makes for a great way to introduce the rhythmic elements of the track. The choreography of the fights perfectly show off the members' abilities and the transitions between them match up very well with the movements of the song itself, and the use of camera angles and effects is flawless; the digital effects . . . well, the flaming hand thing and such weren't too bad at all, honestly. The styling's nice, not my personal favorite, but it works really well for the under-ground vibe, yet it also encompasses some high style trends (the bright colored gloves and shoes to name a few).
I really do LOVE the movement in this MV, the raw power of the fighting has a certain elegance, especially when it's augmented by camera tricks like slow-mo and angle-variance. However, it does get a little excessive, particularly once weapons come into play. The blood on the lens after the brass-knuckles come out seems to be unnecessary, and the ax just seems way too violent. I could have accepted a crowbar, but an ax? Meh, I'll admit that it was a fairly clever method to make a removal of clothing viable (which I'm sure many more people than just I appreciated), but that could have been accomplished with the bent end of a crowbar. Axes, with the whole sharp-blade aspect, just seems like too much. Other than that, I love everything!
Also, it can be taken as a metaphorical interpretation of the industry: the camaraderie of the members, the constant struggle against each other to stand out to the fans (and to management), the way training to best each other makes them all stronger in the end... It's probably not meant to be taken that way, but it could be I mean with their band name being "League of Competition" and all. ^_~
But really, choreography is just SO fluid and wonderful, I'm expecting great thing from them in the future!
