As far as entertainment quality, I am all for Shakira's hip thrusting and butt shaking (she does it better than J-Lo), and J-Lo's pole acrobatics were impressive for a 50 year old. However, that kind of group choreographed "dancing" (more like Jazzercise) is rather souless IMO. And while they both have some decent songs, the whole song "montage" thing doesn't do it for me. Also, I think there was a lot of lipsyncing. That said, it was far superior than the drek from Maroon 5 last year, mostly b/c they suck ass. Generally I prefer when actual live music were the songs is the focus, like Prince which was arguably the best ever.
