Nostalgia. Something you watched as a kid that you used to enjoy. I don't watch it hardly at all anymore. I stopped watching it weekly when i was about 15. I graduated to being obsessed with mma stuff then. But, Wrestlemania is like the super bowl of wrestling. Its worth the $10 i pay for a one month subscription for nostalgia purposes. (This year it was free, because wwe gave me wwe network free for 4 months to entice me to come back). Also, when i have a kid, if my kid gets into it, another reason i would watch it is to bond with them.
I guess I can see that? I mean, to each their own. I'm not judging. I simply don't understand it. I watched WWF as a kid. The CLASSICS, Hogan, King Kong Bundy, Iron Sheik, etc...etc.....and I have no desire to revisit. My son, though, is 5 and he's starting to get into it. That would be a good reason.
