If you all know what a superstar is and want to see a lot of them, don't tune in to "WWE Superstars". A superstar is someone who is larger than life with a lot of popularity, someone like John Cena or Randy Orton. Not someone like Curt Hawkins or Zack Ryder.
You would expect to at least see a few "superstars" occasionally since this show is called WWE Superstars, not WWE Jobbers but that is not the case with this show. This show features the lower carders, jobbers and periodically an upper midcarder but never a main eventer.
This was not the case when superstars first started as Edge, Jeff Hardy, Undertaker, Matt Hardy, Chris Jericho, Randy Orton and John Cena were used for the first few months but then the show became dominated by wrestlers who had no direction going for them. They were placed in random matches without story lines just to give them some air time. As time went on this turned out to be both a bad thing and a good thing. It was a blessing in disguise to those "real" wrestling fans who preferred wrestling over entertainment.
If you watch RAW, you would notice that it mostly revolves around promos with a few matches here and there while Smackdown is more balanced but doesn't provide enough time for one or the other. As for NXT, well, it's a show full of "rookies" so you shouldn't expect great promos or great matches either.
This is where "WWE Superstars" comes in, it is a show that features more wrestling than any other show but not much promos. Superstars is basically the opposite of RAW. Everyone who appears on Superstars gets enough in ring time to execute about a three-star match, it just depends on how wisely those Superstars use their time in the ring to really deliver a good match.
This is where the problem with the show kicks in. "WWE Superstars" gives enough time for a jobber all the way to a midcarder to wrestle a really good match and to show off their skills in the ring but without the in ring presence of a main eventer, those wrestlers will never be given a chance to see if they can last in the ring with the "top dogs".
They will not given many chances to appear on the main shows if the WWE does not have any faith in them. They have already shown that they can put on a good match with other jobbers/low midcarders but without the proper presence of an established upper midcarder or main eventer, the "Superstars" of WWE Superstars will never make it anywhere past that Thursday Night Show.
Just look at Trent Barretta and his current "feud" with an already established upper midcarder in Drew McIntyre. Barretta looks like he can now "make it" with the "big dogs" and he has already been given some more exposure with the current audiences to see if he has a chance at becoming a popular "Superstar".
WWE Superstars is not a bad show, but it really needs the presence of an already established upper midcarder/main eventer so the "regulars" of WWE Superstars can actually become "Superstars" by being put in lengthy matches with those who "made it" to one of the main shows.
WWE Superstars needs Superstars because it could really help everyone involved. The WWE needs to at least try this, because there is nothing to lose and something to gain.
