So I'm one of those weirdos who actually liked the F91 movie despite it having massive problems. For some reason, it had several spinoffs. Crossbone is great, and you'll usually hear about how it's a must read from Gundam fanboys. You'll occasionally hear Silhouette Formula 91 mentioned, but unfortunately, it's completely forgettable and not worth your time. But I rarely hear people mention F90 aside from listing it as something that exists in the Gundam franchise. Having finally read it, I'm just baffled. This is easily much better than most Gundam comics I've read. It's paced really well, the art is good, the action is mostly easy to follow, and the characters, while not particularly deep, are better than the cardboard cutouts you usually see in half assed Gundam comics. It is a little unfortunate that they brought Zeon back when part of the point of F91 was to finally move the series away from that particular conflict, but with execution like this, I can't say that I care that much. And honestly, a faithful adaptation of this would have made for a better film than F91. It's not amazing, but it's a good Gundam story that's been sadly overlooked. If you're a Gundam fan, track this down.
