This was my overall take too. It wasn't a work of great fiction or anything, but it does give some much needed attention to a traitor primarch and goes a bit into why he chose to turn traitor. Unlike most of the others, he didn't do it because he had been corrupted by Chaos or any sort of high ideals. He wasn't even just someone who enjoyed killing like Angron. So it may not be worthy of any literary awards or anything, but it does justice to painting a somewhat sympathetic narrative for the Iron Warriors.
