I don't think this is a bad book or boring at all. But then...I have always liked the combination of what I see Ewing is doing, although I have never seen it done before.
In THEU LIMTATES, we should expect THE ULTIMATES to shine. witha tilt toward the newer characters, as they have to be shown to be worthy of the inclusion in THE ULTIMATES. Characters like America, Blue Marvel and Spectrum have distinctly less recognition zip to the average 616 MU members than do Carol and TChalla. I understand the writing choices he made here.
And TChalla DID notch the most significant physical win in their throwdown with the other supergroup, and he showed his "prep" too, as he knew that Carol would take the actions she did during their group dust up. In flagship books, this ULTIMATES has shown TChalla at least flashing his analytical abilities and his prep more times than he has in any other book except for THE TOTALLY AWESOME HULK. TChalla also showed nearly galactic level tech when he translated from Earth to help The Ultimates with Galactus.
I may be in the minority here, but i definitely like Ewing's book.
