GOOD THING: It's hard to narrow it down to just one given the sheer number of just plain awesome things that happen in this issue. But if I had to pick the best, I'd have to go with the fact that Guy Gardner is capable of using both a Red Lantern ring and a Green Lantern ring at the same time... and kicking copious amounts of ass with both.
BAD THING: While I fully expected Kyle Rayner to not really be dead dead after last issue, I didn't expect him to be back quite this quickly either. Kinda kills the drama.
The Final Verdict: This is one of DC's stand-out titles right now. The one drawback is that it is entirely tied up in the crossover right now, so it's a hard book to get into. Try some of the older trades - you'll be glad you did.
