Technically the Attitude Era is supposed to extend passed even the Invasion angle but most people online regard the Attitude Era from about 1997-2000 or so.
I was the biggest DX fanboy so when Trips finally stepped onto the main event scene, I was very happy. The fact is, while he maybe was never on par with Rock or Austin, he had to carry the company in 2000 when they were indisposed. He is an excellent talent in his own right anyway.
Also he had the most beautiful hair. I would give anything to have hair like he had back then.
Undertaker is my favorite wrestler overall, but when it comes to the Attitude Era exclusively I'd say Austin is pretty much AE personified.
Though The Rock's run is when the ratings really started taking off in their favor in a more permanent matter, so he's definitely a close second. I also loved Mankind and Kane and Chris Jericho during this time period as well.
The lack of DX appreciation makes me want to tell you all two words.
I just watched that episode a few days ago, and then by coincidence the same night he showed up again in an episode of That 70's Show that pumpkin was watching.
I had to explain that was the point in time where he was wisely transitioning from "The Rock" to Dwayne "The Rock" Johnson in an effort to broaden his entertainment appeal.
So far to my knowledge he's been the only wrestler who has successfully made the transition from wrestling to movies.
Austin is all right if he gets a role that suits him, but Rock has more ranges he can reach than Stone Cold.
Suburban Commando was awesome.
