I really hope this isn't anyone's first issue of Invincible, because it's in no way a reflection on how great the series is, the first three hardcovers worth of material at least. What I've read of Invincible has been classic superhero storytelling done in a modern style. This issue attempts to recreate a modern superhero crossover event within the confines of 30 pages and succeeds only in duplicating the over-complication and disappointment manufactured by Marvel and DC in their annual sprawling events.
While reading this comic, you can see the very broad strokes of what the story is, but when you get down into the details it feels rather disjointed and rushed. Major occurrences take place off-panel while pages of miscellaneous Image characters are shoehorned in just so that the book can be called a crossover. Like with all crossovers, the point is to reset the universe to a new status quo and this issue does provide that at least.
Even if this comic isn't always exactly readable, Ryan Ottley does a masterful job of making it a fun book to look at. Normally I would knock off points if I had trouble determining from panel to panel what I was supposed to be reading, but in this case I think that falls pretty firmly on the script.
Do better next time Kirkman!
Oh, and get the fourth hardcover out already!
