Aaron Lopresti's art was nice, but this was a disappointing fight because Captain Atom wasn't fighting back due to "if he uses the upper levels of his power, he leaks radiation" and could "irradiate half of Tokyo." The rest of the JLI can't do anything to Power Girl because, as Booster Gold says, "All we have to use against her is our combined brute strength, and that's not even a quarter of what she's packing!" So all their offense isn't doing squat to PG until Rocket Red uses sonics on her super hearing. Earlier in the issue, we learn that Max Lord's psi doesn't work on someone in pain, so the sonics cause PG to snap out of his control.
I was hoping for a knock-down, drag-out fight between PG and Captain Atom, but oh well.
