After getting in a Facebook debate a couple years back regarding just how wretched the Justin Timberlake Super Bowl halftime show, I decided to review all 52 of the Super Bowl halftime shows and rank them from best to worst.  I have now updated that list to include last night’s show by Shakira and Jennifer Lopez.  The best I can tell is that there is not another list this comprehensive on the web anywhere.  Several websites rank the modern concert-type shows (post 1991), but I couldn’t find any that rank all 53.  If you scroll down my blog a few days, you will see that I recently ranked all 53 Super Bowl games as well, and ironically, the worst halftime show on this list corresponded with the worst game on that list.  It took a little work to find some clips of the other older shows on You Tube, and it is hard to compare the old marching band shows to the current live concerts but here’s what I came up with.  Feel free to comment or debate.
