Justice League: Wild Card: Royal Flush Gang and Joker. Ok, it's a natural pairing, but I don't recall any version of the RFG that had super-powers before. I could be wrong, as I've not read much of them in general, but they always seemed more basic bad-guys to me, and I'm not sure I like making them evil X-Men. There were enough nice touches that I wasn't disappointed overall, but there were too many bits I didn't like.
Justice League: Comfort and Joy: Cute and light. I liked the snowball fight that turned into a different kind of fight. Having a nasty rappin' toy "adjusted" was funny too. The bit with J'onn was a wee more subtle, but very nice. Good touch having him eat cookies that looked like Oreos.
Still having trouble getting interested enough to read my regular comics. The cover aesthetics argument coupled with reference removed by request has lessened my joy in comics to a dramatic degree. I'm going to try and read them, and when I get around to posting reviews I'll use the date they came out as the blog title, as usual.
