I dunno, Raw's been good/decent more often than its been bad since the change to 3 hours but if Vince is serious about change than it can only be good.
Three hours is far too long, yes its allowed for some better TV matches, but otherwise, the show has just been bland. Everything is the same week in week out, the results are predictable, the promos follow the same formula, creativity has mostly been squandered, or if they create something good, its recycled far too much.
They really need to build around feuds more, this is the reason I watch wrestling, yet this is barely a part of the show any more; instead all the other crap gets more time, like touting, tweeting, some random social media ambassador who is interested in wrestling for one episode or else we'll get crap like Brodus Clay dancing cos we've never seen that.
If we get a proper feud, its with the old timers, which do a great job, but at the same time it isn't going to solve the long term problems.
