Lame... just like TNA in general
No, I wouldn't go that extreme. Just their shots at WWE are lame. When WWE does its casual shot at TNA, they are more clever, like when in an article to Umaga they said he was no Average Joe. Or the example you gave about Kennedy and Scott Ramon.
Instead, TNA tries to get a pop from bashing WWE. In the Scott Steiner vs Kurt Angle rivalry, how many times does Steiner needed to say he had defeated Batista, Cena, etc...? The video from Kurt in Connecticut punching Vince Mcmahon.
IN my opinion, TNA tends to hang on the WWE name too much on ocassions. Every signing has to be announced as a former WWE champion(IC, World. whatever).
