WRESTLING IS about how many moves you know, how you execute them, and your in-ring psychology. Sports Entertainment, on the other hand, has more to do with your ability to create a character, give promos, and get people to love or hate you. ROH is Wrestling first, SE second.
No, not at all. ROH is VERY much sports entertainment, because it's NOT wrestling. Professional Wrestling and Sports Entertainment are EXACTLY the same thing, no matter the degree to which they try to promote realism. Sports Entertainment is a term coined by the WWE to avoid being governed by state Fighting/Athletic Commissions, since regulations of Fighting Commissions are much more stringent than those who regulate Entertainment.
And besides, ROH DOESN'T promote the concept of realism in its matches. You can turn on the television and find legitimate wrestling everywhere these days, whether it's collegiate, Olympic, or even wrestling in MMA. How often do you see guys do aerial flips and rolls, etc. in legitimate wrestling? You don't. ROH is EVERY bit as much about promoting little realism in its product as the WWE is. Even if Professional Wrestling and Sports Entertainment were two separate entities (which they are not, but we'll assume for a moment they were), ROH would STILL be classified as Sports entertainment, since their product features wholly unrealistic in-ring work.
As for WHY ROH is so terrible? Because their workers don't understand what I just wrote, or at least, they choose to not promote that way. Now, more than ever, Professional Wrestling HAS to promote based upon entertainment value and its storytelling, because if people want to watch REAL fighting, they turn on UFC. ROH is constantly puts on matches that are wholly unbelievable, and try to get by on the fact it's a circus show, with bunches of flips and extremely fast action.
The problem is viewers can't even BEGIN to try and force themselves to think that kind of action could be real. In the WWE, even though everyone knows it's fake, the best workers can draw you in and make you forget for a moment you're not watching a legitimate event. It's just like going to a movie theater...the best movies are the ones where the acting is so good you don't even realize you're just watching a movie. In ROH, you're ALWAYS aware you're watching a fake show.
There's a lot more to it, but this is the spam zone, and I'm tired of writing. That's just a taste, in addition to what I've already said, as to why ROH is not very good.
