Not really. I think it's pretty cool, actually. He seems more human to me that way, in making him have flaws. I especially like it when he sprints, because I remember the first time I saw it, when the stamina gauge ran out, I thought he was going to fall flat on his face.
I agree with you. semi. partially. i dunno. the way link runs doesn't bother me entirely, but when i first played, the whole stamina meter and dashing and the way he ran striked me as odd. (ooh i haven't used that word in what seems like years:O) i kinda just wish they didn't have the stamina meter altogether. that way, we wouldn't have to stop every time we swing our sword too many times.
In my opinion Link looks cool no matter how he holds his sword =D But usually in video the sword is pointing straight because the player is holding the wiimote like that! You can hold the sword howerver you like, it just depends how you hold the remote!
The reason he doesn't hold his sword while running is because he listened to his mommy not to run with sharp objects also i think he looks beast when he runs like he is trying to save zelda as fast as he can.
