We can't judge Attitude era as good or bad in today's standarts.In that time WCW was ruling the wrestling world and if WWF didn't change it's style maybe there would be no WWE right now.Vince had to do whatever it takes to climb back to number 1 spot.People were bored from cartoonish and colorful characters like Adam Bomb,Doink The Clown,Rocky Maivia...So Attitude era was in that day's standarts was best choice to do and let's see by Attitude era what wrestling business has gained.Stone Cold Steve Austin without his swearings,flippings,beer drinking and rebel to everyone could he be the megastar he is right now.No.The Rock if he stayed as Rocky Maivia did not to cut promos like The Rock is gonna stick smt in your candy ass could he be one of the biggest stars of wrestling that he is right now.No.Mick Foley without his sick hardcore spots could he be accepted as one of the biggest superstars in WWE history.No.Without DX could Triple H get over?No.Look at the ratings WWF got by Attitude era and if there weren't WCW I think those ratings could even go further up to 9's and 10's.So if someone tries to say Attitude era ruined wrestling he just judges it in today's standarts.If today WWE returned back to Attitude era like they did in late 90's it would be a stupid idea in every way(For kids,sponsors...) and I don't think they can make those high ratings again.Attitude era was a fad.Now just look at what is the negative and positive effects of that era:
Positives:
-Stars like Austin,Rock,Foley,Kane,Triple H have borned.
-Made huge ratings WWE can never do right now.
-We started to see much more PPV quality matches on Tv and less squash matches.
-Cartoonish characters that people are bored of at that time were gone.
-Most importantly put WWF in number 1 spot again.
Negatives:
-Blurred heel/face lines.So even today fans give mixed reactions to Cena,Edge,Orton.
-Gained lots of non-wrestling fans that has no interest in wrestling just watch for sex,blood and swears and after Attitude era has finished they have left.
-We had to see some stupid characters and storylines like Naked Mideon,Mr Ass,Godfather,Sexual Chocolate,Young giving birth...
-It was more like a shock tv show than a wrestling show so they've lost some of their long time fans.
What I'm trying to say is even if it had negatives WWE only did what they had to do to win the war.So it was good for the WWE to survive from the war but it had it's some negative effects WWE still tries to fix right now.
