fastlane had great matches with questionable endings and sell. IMHO the New Day promo couldve been executed better, Kalisto vs Del Rio shouldve been on the main card, Axel vs R-Truth match shouldntve been in a PPV, No sense having the Titans win against the Wyatt's as well, I dunno how they're gonna sell Wyatt's match for wrestlemania when they just lost. There's simply not much time for more promos. They turned Ambrose into a jobber again, and Brock was underutilized in that match. Wouldve been better imho, if they went with Lesnar vs Reigns 1 on 1 with Ambrose interferance. Not interested in a Reigns-Triple H main event, probably not going to watch that.
Unless they do something drastic in the Shane vs Undertaker match, whatever ending will be promise to be a lose-lose. Undertaker loses, it diminishes his loss to Lesnar in previous Wrestlemania, Taker wins it comes as a no surprise.
