We don't watch it. My Mom (87) really gets into it. She doesn't vote, but she takes notes on each contestant every week so she can keep track. When she visited us last spring for 3 weeks, we watched with her. It was fun seeing how involved she gets. :) She used to watch it every season with one of my SILs (in their own homes) and then my SIL would call Mom and they would compare notes and have a friendly combat over their favorites. Then my SIL passed away in the middle of the season before last. So two of my nieces went to Mom's each week for the remainder of the season to watch it with her. They really love their GM.
I hope everybody's favorite is the winner. Of course, you'll all have to like the same one. :)
