Can't find the last volume online (and I don't have room for hardcover comics in my house lol), so I'm done with Gundam the Origin for now. The full color version of this comic looks gorgeous.
The prequel portion of the comic is pretty mid. All the lore and extra background stuff about UC0079 isn't really what I find exciting about the series.

I can't judge Yasuhiko too hard until I've seen Venus Wars or Arion or something idk lol. The Doan movie was OK - nothing to write home about. I only saw the first minute or two of the Origin OVA when I decided I'll just wait until GGP gets to it lol. His art and design work is pretty fantastic, though.
A huge part of Gundam for me is watching these characters go through the trauma of losing their nuclear families (through war, death, estrangement, slavery, etc) and eventually seeing them grow by learning to form connections with others, forming different kinds of found families (not necessarily positive growth, and not necessarily positive found families lmao). I think Yasuhiko doesn't quite get this piece (maybe he had decent enough parents idk), and that's why his prequel versions of these characters don't quite hit the mark.
