One of the best elements of Mark Waid's Indestructible Hulk is Bruce Banner. In fact, Hulk himself has taken a back seat to Banner's personal journey towards reconciling his inner green monster with his scientific genius and duty to work toward a prosperous future. Scientific exposition might sound boring, but Waid does it in such a way that presents Banner and his hand-picked team of assistants as explorers of the unknown instead of pencil-pushing researchers. The Hulk only comes out when absolutely necessary.
There's not a lot to complain about in Indestructible Hulk #6. Waid begins a new arc that focuses on Banner and his team journeying to Jotunheim -- mystical realm of the frost giants -- and enlisting the help of the Mighty Thor whilst doing so. Though, not everything is exactly how it seems. The series, so far, has been written a solo book that happens includes a group of tertiary characters who are quickly becoming more and more important. Waid's narrative style lends itself nicely to this setup after a long stint of solo and duo titles.
This issue also really sold me on Walter Simonson's artwork. It's never spoken to me before, and always felt like an attempt at satire that wasn't actually an attempt at satire, and that didn't make much sense to me. Simonson's stye hasn't changed, per se, but it feels more crisp here and less frantic than usual, which is refreshing.
Overall, Indestructible Hulk #6 is the introductory chapter of this story, which means there are some big questions that are left unanswered at issue's end, but the big revelation teased on the cover is somewhat overshadowed by other mysteries Waid planted along the way. There's nothing wrong with that, but it dulls the excitement of the final page, for sure.
