I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
It's about as fun to read as any novelization could be: slick, easy to read, and action-packed. There was one error that I found particularly glaring: "They were armored, their faces hidden. They were humanoid in shape, with monstrous faces similar to the reptiles found on Earth."
To be honest, a simple flip of sentences would fix this. It was jarring to be told their faces couldn't be seen, then to get a description. I feel like the descriptor then the 'but they were hidden by armor' type switch would be less jarring. It's what they'd look like if the armor weren't on, instead of this. It really jumped out at me, too.
It wasn't enough o knock this down even half a star, though. As I said, the majority of it was just pleasant to read. I'm indulging in some brain candy today and tomorrow. I'm already a good deal into Guardians of the Galaxy, but I was out on the beach so I finished this book and started the other before coming home, taking care of a few things, then writing this review. So far, this is my brain candy and no regrets: I'm loving these books. I'm finding it hard to say much against them, and what I do have to say - they aren't as nuanced as adult novelizations - aren't that disappointing. I knew I was buying and reading young adult books, and so I expected these to be not quite as nuanced as adult novelizations.
PS - Coulson is a jerkface sometimes. Like this time: "'Sir, the telephone,' Jarvis said. 'I'm afraid my protocols are being overridden.'"
No contest, Coulson. I love Jarvis more than you.
