Well, damn. I just read BARRIER by Brian K. Vaughan (script), Marcos Martin (art), and Muntsa Vicente (colors). All five issues.
I'm not sure what I was expecting, but it damn sure wasn't this.
That's not a complaint, mind you. I'm actually quite impressed. But if you ask me to explain this story, I'd have to say it's a dash of the movie Arrival (2016) blended with several helpings of current politicos about the US southern border, and then celestially colored with hints of awe and irony (tip of the hat to Muntsa Vicente).
This series gets an enthusiastic recommendation from me, especially if you're bilingual; the book is in English and Spanish (and alien, but I don't think you need to know that third language).
