These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Grant Morrison
Broken Base - Morrison is one of the most polarizing authors in comics to date.
In particular, his New X-Men run is polarizing even amongst ardent fans.
Complete Monster - See Card-Carrying Villain above, then add to that a level of depravity and malice that seems to exist only to perpetuate evil. Be it the brain-washing academy in the The Invisibles, Cassandra Nova's entire campaign during New X-Men or the full despair of a Darkseid-run Earth in Final Crisis, Morrison loves to set his protagonists against pure embodiments of evil and submission.
Mary Sue - deconstructed with Damian Wayne, as many people (including Bruce, his father) think he's an annoying little snit. It's a matter of personal opinion how successful this deconstruction is, since many readers argue that he nevertheless embodies certain Sue-ish qualities played entirely straight.
There's also the fact that in Batman #666 we see a grown up Damian who suspiciously looks a lot like Grant when he takes his mask off. This was actually Kubert's design idea, but it wasn't the first time something like that had happened.
Squick - One of the characters in The Filth is a porn actor with... unconventional fluids. The New Gods' possessing of characters in Final Crisis (Mary Marvel possessed by Dessad, Dan Turpin's... "death" by Darkseid's taking over his mind).
Villain Sue - his JLA villain Prometheus is an excellent aversion of this trope, pretty much encapsulating how to make a Badass Normal a Justice League level threat without dipping into God Mode Sue levels of Crazy-Prepared. While Prometheus does some incredibly Sue-ish things - notably curb stompingBatmanoff panel - he also has crippling psychological flaws, oversights in his planning, and a few kinks in his advanced technology. Essentially, he spends one issue in Villain Sue territory before the sheer magnitude of his undertaking comes crashing down around him.
