I'm going to see the Watchmen film this weekend, so until then, I'm keeping my eyes off Rottentomatoes.com and Metacritic. I've played the demo of Watchmen: The End is Nigh on Live Arcade and, well...it didn't suck, if that's what you're wondering. This one is pleasant, though straight-forward, beat-em-up fare; you choose either Rorschach or Nite Owl II and go around kicking the shit out of pretty much everyone you see. The controls are fairly intuitive: X and Y do various attacks, Right Bumper evades. Pick up tokens in the demo level (set in a prison, by the way) and you acquire the abilies to grab and chain attacks in a limited way. I saw a list of moves online and was impressed by its depth. The game is rather graphic--startlingly so--with plenty of slo-mo finishing moves that occur at random intervals as you fight.
I didn't get to use Rorschach's "Rage" meter as much as I wanted to. Supposedly, the meter fills as you dish out punishment, and allows you access to a few choice moves--"Bullrush" is available in the demo--that allow you to vary the way you dispose of enemies. I still prefer throwing guys over railings.
