It wasn't boring as a whole, but at times it was merely due to the fact that it was utter dominance by DC, and he wasn't willing to risk going 100% which could possibly gas him out in order to finish the fight earlier. In reality he basically toyed with Hendo, who looked pretty much finished(as an MMA fighter) in that fight; he had so many chances to finish him in the 1st and 2nd rounds that he didn't try for. It shouldn't be compared to lay and pray wins because that is not what it was, it was closer to Cain vs JDS 2/3 although there are some obvious differences that separate those fights.
Hendo doesn't even have the weight on him to be a LHW anymore, especially with the new era of monsters like DC, Gus, Glover, and JBJ who could all fight at HW. The guy is almost 44, and looks much worse with every performance, He didn't even look very good in the Shogun win. I think he needs to retire rather than going to MW. No way he beats Weidman, Rockhold, Jacare, Mousasi, and we already saw what happened with Machida(Landed 1 punch in 3 rounds), Belfort(destroyed), and Silva if we assume he comes back well from the injury. He'd have a chance with the lower top ten fighters, but it wouldn't be a high chance at all. He needs to retire soon, no point in trying to be a MW GK at 45, he won't even come close to the belt. Just give him a retirement legacy match with someone like Wandy or Franklin.
