I tuned out of WWE around the mid 2000's, before that point I thought it was decent enough. People who have been watching since Attitude Era and haven't stopped might be able to answer the question better, what episode or moment in WWE made you think that "yep this is shit now?"
EDIT: I'm not saying it's shit now. Right now is one of the few times since I tuned out they have got me coming back weekly and looking forward to RAW. But you cannot deny that the product was trash before 2013. If you do, you must be what Vince says and like everything he tells you to like.
