Much like the first volume, I feel this probably could be a 5-star, but the show adds so much, which feels perfect that the comic feels like it's missing stuff.
This comic ends right where Season 1's main plot does, so I'll go over everything in the show I prefer. Damien Darkblood barely shows up, and there isn't much tension of Omni-Man trying to hide his identity from Darkblood, Cecil or Debbie. The story of Mark being betrayed by Titan works really well before Nolan tells Mark the truth as it leads to Nolan trying to get it in Mark's head that he himself is stronger than anyone else and he doesn't need to rely on people in this planet, something which is later echoed in his chilling monologue. During Mark and Nolan's fight, the train scene just doesn't happen; it was added into the show. But it's such a brilliant, terrifying scene that, again, it feels like it's missing here. Amber is barely even a character, like she only appears, maybe twice? The new Guardians of the Globe get barely anything to do - we don't see much from the Maulers at the moment, and Robot hasn't yet approached them for the cloning, though I believe it is coming soon as Cecil has told him he needs to improve the Guardians rapidly, and I imagine this will be his solution. However, having this take place before Nolan's reveal worked incredibly well because we saw Nolan shift at the end of Episode 1, so seeing Robot work with the Mauler Twins also made the audience question "is he secretly evil too??"
All this is to say, I think the show is better. At least, it is so far. The way it reorders things only strengthens the show, and it feels like the characters are far more rounded. Whilst the comic feels exclusively focused on Mark up until this point, the show made an effort to balance things between everyone. Changing the original Guardians' death to be the first episode changed how tense everything else felt. I particularly love the scene of Nolan saying to the Flaxans, "This world isn't yours to conquer." Anyways, in the next volume, I want to see more stuff from the other characters that aren't Mark. I understand the comic needed to focus on this first to really hook the audience within the first handful of issues (and it does it phenomenally well) but I'm ready to see more from the other Guardians.
