I read this a while back and honestly didn't remember it too much, so I thought I would revisit it, and I ended up finishing it in 2 sittings, which is warp speed for me reading anything lately.
There's plenty of action, political intrigue, and a few questions answered about the operation that was the backbone of the storyline for season one of my all time favorite television show. This comic, while not using the time gimmick very much, did feel a lot like the show with the intensity and action mixed with politics.
I was actually quite impressed with the art, as several characters are absolutely nailed, especially some of the cameos like Sherry Palmer and Richard Walsh, along with even bigger surprises like Christopher Henderson and Charles Logan. Jack Bauer and Stephen Saunders (my personal favorite villain of the entire show) are also spot on, and kick ass like they did in the show.
My only issues were with some of the names being too similar, as there were two characters named David in the book, which seemed unnecessary since there were only so many characters in it to begin with, and there were also two different Serbians named Tesla and Telsa... I mean, why? I also felt that some of the action at the end was a bit convoluted and confusing.
Overall, though, this is a great hidden chapter in 24 lore and a great effort for a comic. I thoroughly enjoyed it and felt it was a solid representation of the show.
