Edge was good. I liked him a lot when he was with Christian. Probably the best team of the Attitude Era. I didn't care for him much from 2002-2004. He started getting good when he won MITB. 2005 was his breakout year for me. He got with Lita, showed that he could work good matches, etc.
He was GOLD in 2006. Slapping Cena's father, live sex celebrations, good matches. His best year in my opinion.
2007 with Rated RKO was good. I still think they should of had Orton vs Edge at WM23.
2008 was another entertaining year for him. Feud with Undertaker was epic. Their Hell in a Cell match at SummerSlam 2008 is really underrated. I'll say it was one of the best ever.
2009-2011 was when I started to not care for him. He got boring on the mic and in the ring. His face runs were bad in my opinion. Edge is a natural heel.
I think he is a TAD bit overrated though. He was good on the mic and in the ring but he got 10 fucking world title runs in like, five years. He got more boring in his later years. He wasn't a GOD in the ring. But he was good.
He deserves his Hall of Fame ring.
