I agree, it's hard to satisfy everyone's musical taste and accommodate everyone. There have been some crappy Halftime shows in recent past but I like the fact they try to switch the genres every year. I find it nothing wrong with diversifying your musical palette, taking a chance I found a crapload of songs outside of my typical musical comfort zone and I love that. An all genre performance is cool but it has to be done right where everything mesh and not sound like a sound clash.
