*takes off nostalgia goggles* The Attitude Era is hideously overrated and - apart from maybe half of the era's PPVs - the wrestling was even more atrocious than it is in today's WWE. Watch any Raw or Smackdown from the era and you'll find it an ADHD-laden experience with crash TV everywhere, shit matches, garbage wrestling and the same old catchphrases/segments being repeated week in week out.
I'm not a fan of most of the ECW original guys like Sandman, Tommy Dreamer, Sabu, Stevie Richards, Rhino etc, or the garbage wrestling matches they held. I only ever watch old ECW for stuff like three way dances and guys like Tajiri, Super Crazy, Psicosis, Jericho, Benoit, Mysterio, Guerrero, Little Guido, Jerry Lynn, RVD and so on. And a lot of those guys also did some of the greatest wrestling I've ever seen on a mainstream American promotion - in WCW. (even during its darkest times)
ROH will not only never make it big, but may even start to fail as a promotion a few years down the line. Their main problem is that any time they build up a legit awesome wrestler that actually has some great mic skills, they seem to get snapped up by WWE or TNA. Having lost Bryan Danielson, Nigel McGuinness, Tyler Black and Austin Aries in the space of a year, not to mention having no previous champions left in the company, (except Homicide) they've undoubtably lost a lot of "star power" in their roster which is a pretty worrying trend. Other indies like Chikara and CZW don't seem to be as affected though, since they'll probably always have their ultrapopular mainstays. (Ultramantis Black, Nick Gage etc)
