I still catch it here and there, usually when home on a Monday night and nothing else is on (or if the MNF game was a stinker or boring), but it ain't even close to what it used to be. I grew up watching Wrestling at the Chase with my dad on Sunday mornings when it featured Dick the Bruiser, Harley Race, Bruiser Brody, etc. That was good stuff.
The banner years for me watching it were both the WWF and the NWA/WCW in the late 80s/early 90s and then WCW in the mid 90s. The nWo thing was like the best storyline ever (before it got too big and they made it ridiculous with everyone and their mother being in it). I didn't really watch the WWF much during the Attitude Era, oddly .
As for Cena, he is damn good. A lot of people seem to hate him, but he is good. He might never be a Hogan, Austin or Flair, but so what?
And I also chuckle at those who dog wrestling by saying, "It's fake." It's like, "No shit, Sherlock." I am pretty sure everyone over the age of 12 knows that. But it is entertainment. Silly entertainment, sure, but a lot of people like that.
Favorite wrestlers of all-time are probably Curt Hennig (Mr. Perfect!), Ted DiBiase (best heel ever), Randy Savage, Bret Hart, and, yes, Hulk Hogan. Say what you want about Hogan, but he was over like nobody's business in the 80s.
