Good series overall
Ironically the action itself is what could've been better (the writing was an unexpected highlight for this type of show), at least in the 2nd half, for the obvious issue of the suits just being a lot more boring in comparison. Though the Zai fight was good at least, especially that first person bit
Yeah it was pretty ironic all things told that the element that should've been an easy 10/10 could have been stronger. I do think most of the mech fights were fine, with a few actually good, but it's more "this is way worse than the 2D stuff" than "this is awful".
