You know, since I've been so critical of Gears of Wars, I might as well say why I may still get the game and am not anti-GOW, just cautious.
Positive Aspects:
-Controls look intuitive and solid so they could make for a more absorbing experience
-It is flat out gorgeous, and even better it runs at silky smooth framerate which will make my upcoming PS3 funded HD-TV a great deal

.
-It looks like it can be alot of fun, how long that fun lasts, I don't know (for reasons I've stated). I'm hoping the demo is just there to give people a feel of the controls
-I do enjoy team based games with AI allies as long as they aren't stupid (I'm looking at you GRAW)
-The visual artistic style may not be unique but it seems to have a good atmosphere
-Vehicular combat could be a blast if done right
-The bosses look stunning
Some other minor concerns (I've mentioned the major ones):
-I'm afraid the shaky camera could get nauseating
-Story, dialogue, acting and cutscenes seem really blah, I am not only hoping things improve here. I really would like to see CoD2 esque storytelling where it is happening as you play
-Lack of enemy variety (I guess this a bigger concern, but this one I can easily give to the gameplay footage being from a demo)
-I dunno the chainsaw looks really out of place
