Before watching this show, I couldn't understand why it had such negative reviews everywhere. Of course, that didn't stop me from watching this my-type-of-action-anime, but I slowly found myself understanding a few possible reasons. Gibiate is animated beautifully, but it has a really bad CGI. It doesn't affect the overall impact initially, but the quality starts dropping from episode 6 where some of the CGI just ends up looking too plastic and at times, unintentionally funny. I still can't understand why the makers decided to go ahead with this style when the non-CGI portions featuring the creatures were so good.
Nevertheless, all's not over for it. Gibiate makes up for it in the form of a solid writing. Right from episode 1, the story unfolds at a good pace and we get to learn a lot about the characters throughout the show. The character moments are deftly handled, and the action sequences, though slightly ruined by the CGI, are still well choreographed and fun to watch. The biggest plus point of Gibiate, however, is its epic soundtrack. The opening music is just out of the world.
If bad CGI still hurts you and a heads up is needed, all I can say is episode 11 has the most usage of CGI and while it looks out of place, the tight writing and solid action save it, eventually leading to a much better and improved final episode. Given how poorly it has fared with viewers, I don't think there's scope for a second season. Still, give Gibiate a try if you like action anime. Yes, it's far from perfect and its single flaw might even ruin it for a lot of you, but it also has the excitement and fun a genre lover would want to seek, while also being open-minded.
