I agree that the invasion angle was done poorly, like the first few weeks were exiting, when wcw stars were showing up out of nowhere and stealing away the wwe title belts(i still remember mike awesome winning the hardcore title in madison square garden, i think that was the pinnacle of the angle right there). But alas, it got sloppy, and then ruined, but thats the way it is. I also agree about the wwe being watchable(cuz I am a huge wrestling fan) but not as much enjoyable. While I have heard some good stuff about tna, I would never watch it, im too loyal to the wwe, but I do hope that tna does get big enough to start pushing wwe(and the creative staff) to do more. Without the competition(unless you call monday night football competition) wwe has become lax, complacent, and because of this their stories have not been good at all.
If the wwe wants to get back to the old attitude era(and i hope they do) there was one thing that constantly stuck out to me personally, and made the wwe both interesting and unpredictable. While it did have its mega stars in Austin, the Rock, HHH and so on, the thing that made the attitude era big, and on the flip side also made wcw big, was the stables. With the stable creation, the backstabbing, the new friendships, the new rivalries, stables were what made the attitude era run, and everyone involved in wrestling were involved in a stable in one way or another. You had DX, the Nation, Corporation, Ministry, the Corporate-Ministry, Radicals, these were some big stable groups that created so much interest and intrigue in wrestling. I am unsure if this would work with today's wrestling, as with the brand separation's, the number of wrestlers available for a stable are small, as the star power is small right now. The only way this would work would be for the brands(at least raw/smackdown) to come back together, but that won't prob be the case(at least for the next couple of years anyway) so who knows. But again, I think stables are what is needed to make the wwe enjoyable again.
