First of all, this graphic novel appeared after the Gundam Seed Destiny anime so yea, the story is exactly the same. And probably that's the reason it is not very popular either. For a fairly long anime adaptation, these 4 volumes are pretty rushed.
As a huge huge Gundam Seed fan it is hard for me to try and stay fair to the actual quality of this hence why I actually bought this in the first place: if you really really love something buying it feels like the right thing. Plus I am pretty sure at a first glance I couldn't even find any online source
Because it follows the exact story in the anime it couldn't be worse than it. However, it is kinda rushed and at times it does feel that I am probably enjoying it a lot more simply because i know what happens in the parts that are actually missing. For example Shin's story isn't as emphasized. On the other hand, because the personal things are not as detailed as in the anime, could be a good thing for the people that are more into action scenes. The gundams appear every 2-3 pages at least.
I can't find any flaw to the art. It is very clear and neat yet detailed. Ever felt like you don't understand just what the heck are you looking at? Every panel (and I'm mostly talking about fight scenes which usually make problems) are crystal clear, no confusion at all. The fighting scenes are great and the dynamic is well executed. My only problem would be that the characters don't really look like the ones in the anime.
Well I loved the anime because I could connect to the characters. Since things are rushed in the manga, as I have previously stated, the characters insight is pretty poor. I'm not at all pleased to how Shin looks rather a crazy dumb tard than an angry, revenge motivated rebellious thing. He was kinda hot in the anime, here is kinda... not.
Enjoyment: 10 - outstanding
Because I am a seed fan enjoying all the tension moments here at my own will it feels awesome. I am a kinda slow "watcher" and since I specifically like how the fight scenes look like here overall I am perceiving this as a bit more dark than the anime where I usually lost focus. I wish they would just put some sort of soundtrack to the pages too
Overall: 8 -because there isn't anything new and because it was rushed but this still means "very good" right?
