I have seen the ECW guys in recent IMpact episodes and it is decent. Sure they are old but if they can still go who cares. And it isn't like they are being pushed hard. Looks more like they are being used to draw more eyes to Impact and help out some of the younger talent in Impact.
But I forget to some fans anything Impact does is "Dumb" and "LOLTNA".
As long as they aren't going over everyone and becoming a focal point of the show I don't mind. But it's odd seeing them as Impact has quite a talented, young roster and they aren't really needed. I think a lot of it has to do with Callis's ties to ECW and probably seeing some value in bringing in lapsed/ECW fans.
