So I was watching one of the Undertaker dvds and thought "hmm, which era of the Undertaker's career was the best?" Personally I think there was four eras starting with the "Zombie" era from 1990 -1997, the "Dark"era from 97-99, the "Badass" era from 99-03, and the "Deadman" era from 04-present. There's a lot of factors going into this including title reigns, match quality, Wrestlemania impact, fan connection, as well as the presentation of the character. My personal favorite was the Badass phase, although I think the Undertaker was at his peak around 98-99 at the time of his feud with Kane and the Ministry of Darkness. Thoughts?
