That feud seems completely irrelevant at the moment. It's one of the only feuds this year that is actually new going into Wrestlemania and not main event rematches, yet it gets one measly in-ring promo a week and nothing else. Any feud with Undertaker should consist of LOTS of backstage segments imo; backstage segments have seriously lacked in the last few years with WWE. The whole feud is based on CM Punk playing mind games with Taker, but so far all he has done is steal the urn and show disrespect to Bearer/Taker with it. It just seems lacklustre at the moment for a feud I have such high expectations for. CM Punk is obviously running out of fresh content to actually say and I don't blame him. Especially as Taker can't really compete with him in a back and forth and his character sort of stops that opportunity anyway, so we're left with Punk running his mouth and Taker sometimes appearing. Once again, the word LAZY comes into play. It's simply lazy booking imo.
