Well back then that performance was a tragedy ...... but right now its one of her most iconic performances of her career
I think the performance represents the sickness, weirdness, falling, auto-destruction and darkness of 2007 Britney Spears , I think infamously and ironically fits "Blackout era" very well, just like the raunch low budget music video and the sick auto-destructive lyrics of "Gimme More".
