He's the main event heel for Raw right now, feuding with CM Punk currently.
His return to the WWE was honestly one of the most brilliant things I've ever seen. He made a bunch of cryptic videos mysteriously hyping the "end of the world as you know it", and after months of these, he arrives on Raw and basically just does this really over exaggerated fan friendly return. He spends like, literally, twenty minutes doing nothing but pumping up the crowd and screaming "Yeah!" and "Come on, baby!" and being this cheesy goof. When he finally gets the mic, he just stands there smiling and cheering, and doesn't say anything.
Next week, he does the same thing, but then randomly breaks down into tears and leaves. Week after that, he gets into a tag team match, makes everyone hyped for him when he gets tagged in, basically pumps up the crowd with taunts, and then just...leaves the match, without doing a single move or getting hit once. Then he does another promo where he wastes ten minutes just being a goofball. Long story short, he does this shit for several weeks, eventually attacking CM Punk and making an epic promo about how he got the fans to cheer for him just by screaming like a moron and says and I quote, "I just trolled you all".
Warrior is/was garbage in the ring and such a prima donna with a fragile ego. He's also a raging lunatic. I'll give him the fact that he's one of the most intense workers in the biz, bar none, but everything else? He fails when compared to Chris Jericho. Hard.
This has been a good decade if you go 2002-2012 so far. I think the in-ring work is better than it has been in a long, long time, and the story lines are getting back to the point where I'm engaged enough to tune in. Attitude Era is still pretty epic, though.
I'm not a fan of Jericho and comparing him to Ultimate Warrior, one of the best wrestlers of all time is insane. You might need to relook at what Warrior has accomplished. You might be playing with all of this though...I don't (hope) think you are serious.
80s - 90s was a good time for wrestling. Rock, Austin, D-X, Bret Hart, nWo before the suckage, etc...
Really, though, WWE has stepped up its game a lot, probably due to the fact that you have more wrestlers working behind the scenes and there's a lot more fresh blood in the company. The matches are solid, angles are pretty good and not as predictable as before. And hell, they've even made John Cena matches/angles interesting, which is...crazy.
