Not having read a many Titans books over the years, I thought Henderson made a decent attempt at introducing the various characters. She may have gone a bit overboard on Bombshell and Beast Boy however as they were annoying to the point of being distracting from what little story there was. I'm sure there's probably stuff going on here that means something to Titans fans, but as a relative n00b there wasn't a lot to draw me in. Overall, this didn't seem to flow all that well. Dialog often felt disjointed and unnatural, especially the last 8-10 pages. It wasn't all bad though. Wonder Girl's portrayal as a leader who was unsure of herself seemed pretty well done, but this was probably the first comic I've read with her where she wasn't spending most of her time crying about dead Superboy so maybe I just liked that this was something different.
I've never really liked Bennett, but the art in this helped the comic a lot. It was actually easier to follow what was going on by looking at the art than it was by reading the balloons/captions. The last splash page with the monster thing was pretty sweet, if the comic had been better maybe I would be interested in seeing more of that.
It seemed pretty damn weird to get an introduction story in the main part of the comic only to come to the backup and find out that it's part four of an ongoing serial. What was there seemed decent enough, a bit by the numbers maybe, but decent.
