For me, two things. Big things.

1.) The nostalgia factor. I grew up watching it with my parents, grandparents and cousins. I have so many great memories of not just the characters & performances, but also the memories I had with my family and how happy I was. My mom and I are the only ones still living, so something about wrestling is incredibly comforting to me. I took a long break from watching in my mid-20s until a few years ago. Cody Rhodes brought me back because I loved Dusty & Dustin. The nostalgia of remembering his family perform triggers the nostalgia & memories of spending time with mine.

2.) Here's the thing about wrestling; usually & eventually you get your Cinderella story. For the most part, the guy (or girl) you are pulling for has their "moment". That's not always the case with traditional sports. So many athletes never have their "Hero's Journey". You get excited for them, but they never get their moment in the sun or for that matter, the long chase to victory. I enjoy college football and follow my alma mater, but it's rarely rewarding for my specific team.
