Having tried this on various occasions, I must admit that my liking for it has varied quite a bit. It's never struck me as offensive or particularly unlikeable, just sometimes a bit "blah" with too much grain influence. Yet other times, I enjoy it a lot more, liking the whole coconut/vanilla/malt palate, which has some nice sweet aspects to it (that must be from the plum wine casks that play a role in the maturation). And even though it still tastes grain-y (particularly in the finish), it doesn't bother me as much. I think that the more I get to know this, I've found it to be a generally agreeable blend, certainly preferable to many others.
I tried this in a master class at Whiskylive Los Angeles alongside all the component whiskies that make up the blend. This is a pretty decent blend, but suffers from the same issue I have with almost all blends, i.e. it has been designed for drinkability and lacks any distinct flavors. A little grain on the nose, followed by caramel, honey, and some grain notes on the palate. I'd say I enjoyed most of the component whiskies more than the blend itself, in particular the plum cask matured single malt. It is a very well crafted blend, however, and I'm sure any blend drinker would be happy with it.
