Until you mentioned it, I was struggling to remember who played last year's halftime show...and I vaguely recall some dust-up about Adam Levine disrobing at the time? I do remember Maroon 5 being mostly underwhelming last year. Music was good last night...I expected the costumes and dance moves that we got, because, well...Shakira & JLo. I've always preferred the former to the latter over the years...but both did well last night (charges of apparent S&M regalia notwithstanding).
Honestly, I don't always pay much attention to halftime, because the quality of the shows is so variable...or I just don't give a crap about some of the artists. Some of the standouts over the past 15-20 years (IMHO) include Prince, Katy Perry, Bruno Mars, Lady Gaga and The Who. Not a huge fan of every one of those artists...but they put on awesome shows.
On a related note, this year's crop of SB commercials was mostly forgettable...however, the Rocket Mortgage commercial w/ Jason Momoa "stripping" off his biceps and chest gave me the heebs, kinda like the "PuppyMonkeyBaby" Mountain Dew commercial from a few years back did.
