I quite like the adventure, so it’s mostly a taste thing.
I don't agree.
Whether you like something or not is taste.
Whether something has these issues - which you may choose to overlook - is a matter of fact.
And you've presented your taste, as if it's equal to his facts and analysis. It isn't. Period. And I say that really not liking the Alexandrian, personally. But he's done a serious analysis and breakdown of the issues and peculiarities of the adventure, and you saying "It's just a matter of taste!" in that context is,
at best entirely unhelpful and uninformative. It's not, actually, just a "matter of taste" whether a map doesn't have a key, for example.
Despite my distaste for the fellow, he's one of the few people left who I'd trust to actually review a WotC adventure. Sure I take his taste-based opinions with a lot of salt, but he picks up on really serious flaws and issues with adventures that the much lighter-touch reviews that 99% of D&D reviewers do, absolutely do not, and that often only emerge once people start running them, and indeed have done so for some months.
I'm glad for this review because I was actually thinking of picking this up, as LMoP was so good. Sounds whether you like it or not, this adventure has none of LMoP's good qualities. He likewise convinced me not to pick up Dragonlance, because he pulled out a number of flaws which would have absolutely driven me around the bend if I'd tried to run it.
