This series is boring. Nothing really happens. The Skrulls attack, the heroes fight, some get defeated, a new batch of heroes appear, they fight more Skrulls. Secret Invasion is like a boring superhero version of Ground Hog Day.
Plus, Yu is not the best storyteller. He is great with a book like Ultimate Hulk vs. Wolverine, where it's two major characters who are featured. But in a book with dozens of characters, sometimes appearing in a few panels, his style and artistry are not up for the task.
This book requires clear, visual storytelling -- otherwise, the small plot twists lose all impact.
This is a massive disappointment. But aren't all events?
