So this book contains the actual Annihilation event and damn is it brutal.

The first few issues build up the war one last time giving spotlight to a few underused characters. However, it's the 6 part Annihilation event that really shines. A brutal tale of war and carnage that rocks the cosmic world. With Nova trying to lead the defense best he could, with Kree army lead by Ronan, Peter from guardians, and a few other characters they try their best to stop Annihilus and his army.

The sheer force of Annihilus and his army is crazy. It's also insane to see some elite warriors as Galactus and Silver surfer suffer a horrible consequence. But the brutal war has a HELL of a payoff as issue 6 is one of the best endings to an event ever. The art also stays really solid showing off some major epic fights. The last part of the book is kind of a bummer as it's the aftermath but not very interesting except save for a few silver surfer moments.

Overall, the actual event is fantastic, even if the rest isn't as good, so I'll give it a 4 out of 5.
