I'm giving this Omnibus (The Gunslinger, green cover) five stars based on a stand alone production. If I were to compare this to the first Omnibus (Dark Tower, maroon cover), I would only give it 3-4 stars. As a constant reader and fan of the DT series, I am certainly grateful to have both collections; however this Gunslinger Omnibus was not as good as the DT Omnibus.
Some aspects I enjoyed were the illustrative effects taken to the first DT book: The Gunslinger. It provided an interesting take on Roland's (backwards) adventures of meeting Brown, the events at Tull and the Way Station, and interactions with Jake and Walter/Marten. Seeing an illustrative version of a well known story is always fun and exciting.
There were also additional stories added to this Omnibus that were appreciated, such as a few side tales of Roland's adventures while wandering through the desert (Not-men, Sisters of Eluria). There were also new stories- Sheemi's Tale, Roland's ka-tet ambush of Farson's men, and So Fell Lord Perth - that were fun and interesting as Robin Furth and team expanded on the DT universe.
For all the fun and newness of this Omnibus, I have to say one drawback was not getting Jae Lee onboard. Lee's illustrations and work on the first DT Omnibus is outstanding. His artwork captures the complete essence of Mid-World and the DT universe. Richard Isanove joins the creative efforts on this Omnibus and because he worked on the first with Lee, you can see how his style carried over into the Gunslinger Omnibus. If I'm being honest, the other illustrators and artists that joined The Gunslinger Omnibus do not meet the standards that Lee and Isanove established in the first DT Omnibus. The Gunslinger artwork is good in a vacuum, but no where near the quality that Lee/Isanove captured.
I also want to point out that the Companion book in the Gunslinger Omnibus is not at the same level as the first DT Omnibus Companion book. The Companion book in the DT Omnibus is nearly the size of all five volumes of the DT comic and chocked full of extra content, interviews, artwork, sketches, folklore, tales, and expanded content. The Companion book for the Gunslinger Omnibus is maybe half the size of the five volumes of the Gunslinger comics and does not have any interviews or expanded content that the first Omnibus Companion book included. It does have Robin Furth's notes and introductions to each Gunslinger comic volume and also offers extra sketches and notes to some of the illustrations. The the Companion book is satisfying; however it does not achieve the level of effort that the first one set out to do.
It may seem like I'm being hard on the Gunslinger Omnibus, but it's only because the bar was set so high on the first DT Omnibus. All things considered, I am very appreciative to have this Omnibus and look forward to Marvel doing future editions of the DT books.
Pros: Marvel adapting The Gunslinger to comic form and bringing the pages to life.
Cons: Not as good as the Dark Tower Omnibus that came out a few years before this Omnibus.
Bottom Line: For any fans of the DT series or for anyone curious about the DT series you will still enjoy this collection.
