What did I miss?

Hey guys, I started watching wrestling (always WWF/WWE) when I was a kid. I'm 33 now. I grew up without cable, so what I saw was limited. In high school I had a friend record Raw for me, during Austin's time and DX's time. I watched all the way through college and a little bit beyond, and gave up wrestling around 2005, 2006 until I want to say 2011 (I remember I picked it back up a few weeks before the WrestleMania that started with Sheamus beating Daniel Bryan in 18 seconds or whatever it was). So, I'm wondering in your opinion, what is the most important stuff that I missed? What fun stuff did I miss? What were some of the big rivalries during that time? What were some of the cool factions of that time? In general, what was YOUR favorite part of WWE during that time?



Thanks for your input!
