Query: Ultra violent vision of Thor from the great Garth Ennis

Collecting the five issue mini-series by our favorite mad Irishmen scribe Garth Ennis (Punisher, Preacher); Thor: Vikings finds the classic Marvel hero defending modern day New York City from an immortal clan of blood thirsty vikings. The storyline and presentation is pure Ennis style mayhem: loads of bloody violence combined with an outrageous sense of dark humor; a combination which made his works on The Punisher, Fury, and Preacher so sucessful. The art by Preacher cover artist Glenn Fabry is more than solid artwork, though Darick Robertson (who did the art for Ennis' Fury and the recent Punisher: Born) would have been a better choice to illustrate all the bloody carnage. While Thor: Vikings is a great read to be sure, it doesn't strike the same gold as Ennis' previous works, but it doesn't try to either. All in all, fans of the great Garth Ennis should check this out.
