If I am giving my opinion then I must use the word I, becauseit is my opinion. Unfortunately it seems as if my opinion has turned into negative critisism which was not the intention, but since you need an explanation of what pushing the envelope is , then I can tell you to referrence the FX crew of the 90's and early 2000's which was revoutionary for its time to give you a better understanding, which is probably what influenced you to write. As far as contributing, that's on you, your the one down. Nuff said.
