I'm mixed on Triple H as new head of creative (if, indeed, Vince's retirement is more than just a PR smokescreen). His booking in NXT 1.0 was solid, sensible and generally optimised wrestlers' strengths. Weekly TV was really quite dull but it built well to what were some excellent PPVs in terms of in ring quality and the 'sporting' feel of wrestling.
HOWEVER, NXT did turn into an indie super fed with work rate prized over stories and actual character developments. The ring entrances were usually very impressive but barely anyone had any depth or personality beyond that. And, as I said, weekly NXT shows were generally snooze fests with some decent moments scattered throughout.
Having said this, I'm glad WWE should hopefully freshen up and there's a booker who generally sets up to maximise the talent and take titles/matches seriously rather than make everyone bar a select few look silly. I hope Triple H draws upon the creative team from NXT 2.0 as, in my view, they have done a far better job than NXT 1.0 of establishing actual characters. It's been hokey and raw in places (though that's partly because it's an actual developmental now rather than a glorified indy) but it's been exciting, fun, different and everyone has a discernible character more than just 'good wrestler'.
