Finished last night. Now I have #103 - current coming in singles next week.
MY REVIEW OF THE SERIES (in a nutshell):
No spoilers (promise )
If you start out reading Invincible and get through the first 20 issues or so, you might walk away and think, "Nah, this isn't for me... just not enough going on and it's a little premature for my taste." I was kinda thinking the same thing. I start the series several months back and made it half way through the compendium one and realized that it hadn't really captivated me like other series had in the past.
Over the Christmas break I had a chance to pick up compendium one again (mid-book) and was determined to finish it. Before I knew it I had finished the first book, but toward the end I thought, "I need to order the compendium two so I won't be left hanging." Kirkman does a good job of layering multiple plot points. He'll start a story point (either as a major sub-plot or humorous interruption sub-plot - thinking the Squidds people and his broken English) and weave the plot along the main arc and this happens well over the course of the series to date.
By the end of the first compendium I was totally enamored with Invincible.
But, that was just the beginning...
The second compendium (as other Invincifans have foretold) was the real payoff. The confused teenage persona of Mark Grayson is faced with many tough decisions and things get serious quickly. Conquests was a terrific villain, along with Thragg, Angstrom Levy, PowerPlex, the Squidd, etc. The Viltrumite War against the Coalition of Planets was a winner and the Dinosaurus storyline was also good.
I should also mention the Ryan Ottley does a fantastic job with the art in the book.
All in all, for $90 you can buy 90% of the series and have a great time reading the first two compendiums. No regrets here and I know I'm headed back to #1 in the future to start the journey again.
