Just to start off - I say Batman's out-of-character, especially in the super-criminal fight with Superman in Metropolis. The idea of Batman saying he likes because he's 'sunny' is wrong on every level, Batman's supposed to be a creature of the night (although less so in the Justice League) and this would have worked if any character other than Batman had said it
Rant over, I thought the Superman/Captain Marvel battle proved intresting, and showed just how strong they both were, the point of that battle though seems rather unknown to me... "I'm trying to be reasonable so you hit me through a wall" seems rather unlike Superman to me, though I do agree with another review that said Marvel should never have challenged him at all.
This is another chapter in the CADMUS Storyline, where Hamilton shows his allegance to CADMUS, if a little cryptically. Luthor obviously set up the entire thing, raising suspicions about him.
Like I said, it's a shame how Captain Marvel quit the League, it would have been interesting to have learned more about him, and his 'share of pretty nasty bad guys'
All in all though, it was a pretty decent episode, so that's why I give it an 8/10
