Expanding this topic won't get you very far. NMA isn't exactly an anime-watching crowd by and large.
I myself don't watch much of it, because by and large the good majority of it is shit. Not everything has to be on the level of GITS: Stand Alone Complex, but the problem a lot of writers seem to have with creating shows that are just fun is that they confuse being fun with being stupid.
Granted, a lot of humor is regional. Some white boy from Oklahoma probably wouldn't be able to get vague references to Japanese pop culture (Does Family Guy translate well with foreign audiences?). Yet most publishing houses seem more than happy to just take moderately succesful manga and then do a by-the-numbers recreation of it in animated form. A lot of times like in the case of Full Metal Alchemist or Azumanga Daioh, you get good results. The problem though, is that any idiot can write a manga, and there are tons of other idiots that proceed to lap it up. The end result is a lot of shows that recycle the same conventions over and over again with a different setting, or characters. (take for instance, Inuyasha compared to Fushigi Yugi)
In other words, animation studios and their backers aren't willing to take a lot of risks. The end result is a media that's over-saturated with a bunch of the same old uninspired crap.
Note: The WWE is what's left of the old professional wrestling federations. All you need to know about "Professional Wrestling" in its televised form, is that all events on the show are pre-scripted into a soap opera for cretins, and that with the exception of injury or accidental death, none of the matches have an outcome that's based on competition involving the ability of the performers.
