Hm.... Well, I liked the second half a lot more than the first. Seemed a lot more mature, most of the whining of the sniper was gone. I think if they made more with these characters, it could be alright. Still don't like the drawing style, but that's just preference, and doesn't really matter.
Also thought it was interesting how the marine who was trying to get in with the ODSTs at the beginning got all cocky-a55 near the end. Pretty big character change. Good ending situation, but I think it would've been better if he had been cocky throughout. Again, just my opinion.
I suppose I have a tentatively renewed faith in these projects. Hopefully the others will reinforce that.
