Should be an entertaining show if nothing else.
For all those voicing negatives, who else would you put up there (that has name recognition, which is what the halftime show is about)?
top of my head...hmmm
Chili Peppers (deserve more than a 3 minute cameo, they are incredible live)
Green Day
Ariana Grande (not a fan but would pretty obviously be a drastically better draw)
Taylor Swift, has she done it?
Rihanna, has she done it?
Arcade Fire
Adele
Not a country music fan but guessing there would be a few bigger names than Maroon 5
2 or 3 of these may tell them to pound sand given cave subjects.
