In other words, there's really nothing bad about it. On the other hand, there are some positives.
There is one negative consequence that comes out of this, a minor one no doubt, but still a negative. That is, taking the title off of Nak in the first place sacrifices continuity for a moment that didn't really need to happen.
The point was, you know the Japanese tour is coming. Part of the reason you're doing to tour is to build the WWE and NXT brands in Japan.
I get this, and I knew it was going to be one of the main points opposing my OP. Still, I think some people are putting too much stock into this particular point as a justification for lame booking. In all honesty, Japan eats up anything WWE anyway, they always have, and having Nakamura on the card alone would have drew fans to the event. My point is, you didn't
need to give Joe the belt just so he could lose it in Japan. Having Nakamura defend would have accomplished the exact same thing in this context without sacrificing the continuity of his run.
You could keep the belt on Nakamura, and have him defend against Joe or another repeat challenger, but one who's a credible threat. Nothing wrong with it, but ho-hum. (5.5/10)
You could have Nakamura defend against a new challenger, one who's not going to win the belt. That shorts the Japanese fans a bit. Say 4/10.
Or you could have Joe win the rematch and take his belt back, and have NAkamura come in as the babyface hometown challenger in the climax of a triology. Japanese fans go home extra happy, which should pay off down the road. (7/10)
See, I have a problem with this type of thinking. How exactly are you calculating these scores. I could just as easily say: Nakamura defends against Joe in a great match. (8/10)
Nakamura wins title from Joe in a great match. (8/10)
But these literally mean nothing as they're just my personal opinion.
As someone else said, I'm not sure what more you expect from the NXT belt.
The NXT belt has been booked well because it hasn't been hot-shotted like this in the past. When Finn was defending against Owens in Japan, they didn't take the belt off of him and hurt his run just so he could win it back "at home". Sacrificing continuity for the moment works sometimes, but I've never been a fan of that particular booking.
To each their own though. I can see both sides of the argument, but I personally found it rather pointless.
