The artwork isn't bad. But I don't see these two things going together. The Trek philosophy of "every life form has a right to exist" just doesn't bode well for how this would all turn out - otherwise it's just a "let's kill the bugs!" story. All fine and well for an aliens story, but it ain't Trek. Look how muddled the whole borg thing got. Also, the image of Spock trotting around the Enterprise with the vulcan weapon strapped across his back just doesn't ring true to me.
Good point, although, to be fair, in "Operation--Annihilate!" nobody seemed too concerned with defending the neural parasites' right to exist!
