Some reviewers here have criticized The Red Wing for not being longer, but I thought the length was just right when you consider the ideas involved and the execution. I read The Red Wing in one sitting, then reread it immediately after. Many scenes with caption boxes take on a slightly different meaning once you know the "ending" than they did isolated from that context on the first read. The Red Wing is an exercise in economical storytelling. It may be physically short, but it is also dense with ideas and possibilities. Multiple readings will be beneficial or even necessary. To the extent that The Red Wing encourages at least one rereading, it isn't really a short work.
The use of time travel in this story is purposefully structured in a way that disorients the reader. Hickman spells it out for you that time is not linear early on in the story. The use of ouroboros (the snake eating its own tail) on the cover is also an early indicator that this will be a non-linear experience.
I don't want to reveal much more about the story other than that it involves time travel, and that once you understand the story, it raises a lot of questions not answered by the text about the characters. In my opinion, these are questions best left unanswered. The hints and suggestions made throughout the story are probably more interesting than a bloated story that spells out exactly how (and when) everything happened.
Pitarra's art is great throughout The Red Wing. Fans of clean line artists like Frank Quitely, Seth Fisher, Geof Darrow, and Chris Burnham will love Pitarra's art in The Red Wing. And the best part? This is Pitarra's first major work. I look forward to watching him evolve.
In short, if you enjoy science-fiction, smart, minimalist storytelling, and works that have repeat reading value, I highly recommend The Red Wing.
