I agree about Flash. I liked it a little bit more than you, but I had all the same issues. I will say that I think the guy at the beginning is your boy, Zoom. And I don't mean Hunter.
War of Kings was really good, but lacking in the huge moment of the first issue. Great stuff, but a little subdued in some ways. Totally agree about the moment with Crystal.
Secret Warriors was good fun and interesting again. Plus, an actual action scene. Poor Yo-Yo.
Trinity was solid again. Loved seeing Enigma's reaction to the CSA.
Teen Titans was a great little, new team issue. However, I am not picking it up again until after the crossover and I didn't get the annual. I do love the new lineup though.
JSA, I don't know what to say. Taken on it's own, it's a solid enough issue. However, they ruined the Marvel family. Like, really really ruined it. I don't know why DC hates the Marvel family so much, but they do. I do think that was Modru at the end, so that should be interesting, and I did like the team building stuff and the stuff with Atom Smasher and Black Adam.
Invincible Iron Man featured too much Pepper (which is a subplot I just don't care for) and a really poorly handled Hill, but it also had an awesome Namor and Tony, so I'm torn.
Overall, a solid week with some big disappointments.
