Arrogance
It seems I'm the only one who was annoyed by the arrogance and "tough guy" attitude of the GI Joes themselves.
I mean seriously... what's with all the tough guy bullsh*t?
"we're the alpha dogs", "when I see a target, I TAKE IT DOWN!", "emotion can't be rationalized" and of course, they HAD to put in a scene with guys doing bench presses didn't they.
I know it sounds stupid, but this annoyed me. And it was not redeemed by the weak plot and cheesy lines.
