What makes you a geek?

[Zingydex]

Han Shot First.

That only matters when geek points are being considered.

I'd say it matters quite a bit when you consider the plausiblity of the scene from a professional reviewer's standpoint - and they love to pick stuff like that apart to use as ammo for giving thumbs down to all things of interest to geeks. Greedo couldn't possibly have missed at that range, nor could Han have outright dodged the shot. The only way he could live to continue being part of the story is if he shot first.
