The skinny chars are ok, i think its stupid looking but its simply a stylistic choice. The problem is trying to make the main character a genius, but making him a dam fruitcake with a constant dumbass internal monologue doesn't equal genius. Also, the giant robos look alright, i like the 'let's deny physics by running up walls' but that's ok, the amount of friction would burn the wheels and walls aren't generally built for that kinda shit but w/e.
Is there any reason I should keep watching this at all? Good character development, pure awesome lines, intriguing plot?
