I agree with the other two reviewers of this item (and the fact that only TWO folks bothered to review it should be an indication of what you're in for).
I would give this two and a half stars if I could, but since I have to go with 2 or 3, I'll vote on the side of generosity and give it a '3.'
In DREAMWAR, several DC superhero groups mysteriously pop up in the Wildstorm universe and start attacking everyone, only to slowly realize that they're being manipulated. The survivors of this comic company crossover-clash eventually team up to deal with the genuine threat, a somewhat anti-climatic finale before the abrupt final curtain.
What worked for me was the decent art, and simply the spectacle of seeing several DC and Wildstorm characters together on the same page. Keep in mind this story was written pre-DC Relaunch era, so it wasn't everyday you got to see Stormwatch take on the Legion of Superheroes, or the Teen Titans take on Gen 13. I also liked seeing the resurrected/reborn Jenny Quarx. For me, her presence gave the story a solid reference point in time for the Wildstorm universe characters.
What DIDN'T work for me? The overall story in and of itself should have been a longer piece--perhaps a 12-issue maxi-series, which would have given the writer time to fully explore the many fight possibilities as well as the team-up possibilities. We get very few one-on-one combat scenes; most of the battle is chronicled through splash pages or wide panels of amalgamated and/or aggregated battle scenes. Also, several DC villains are thrown in--most notably Doomsday, but we don't see any Wildstorm villains. The concept of the Sun-Eater (another DC horror) is introduced for the climax, but the way the final sequences play out leave you underwhelmed and yawning. Yes, there's the very real danger that Dreamwar just may make you yawn.
Keith Giffen is generally a decent writer, but this tale falls somewhat short. Could have been way better with maybe 6 more chapters to carry it out fully. If you're a fan of these types of company crossovers, might be worth reading, but it is FAR from the best crossover adventure I've ever read. And considering that the recent DC relaunch has integrated several of the former Wildstorm characters into the DC Universe proper, this book may be quite moot at this point. Last time I looked, someone on Amazon was offering it for $3.50 plus shipping. Willing to gamble a few keyboard clicks and a PalPal disbursement to check it out?
