Aye JMS is still on Amazing Spiderman, and with the current civil war storyline is on a role, as good as the Morlun days.
Really Civil war is a great boon for JMS because it's allowing him to concentrate on the Character motivations etc something he does fantastically, while avoiding some of his... problem areas. (Such as the Retcon from hell, Gwen Stacy having kids with the green goblin before he threw her off a bridge...)
In anycase as I said JMS's run in Civil war rates up there with the original Morlun story for sheer greatness, and is in me humble opinion the highlight of the Civil war event.
