This is by far my favorite Hulk related series. Greg Pak does an excellent job with Bruce and the Hulk keeping them separate and the same all at once. The battle between Hulk and Skar was done perfectly and ended the way it should have. Both of these men displayed insane levels of power, but Skar using the earth's tectonic plates was a well thought out way to enhance his abilities. Pak also does a good job showing the impact that the battle is having on the rest of the marvel universe.
I'm looking forward to find out what happens when the Hulks other son arrives on earth. There's a lot of Hulk characters running around currently, which will almost certainly change before things are finished. I trust Greg Pak with the Hulk on every level, and can't wait for the next arc.
