I watch my brother play hearthstone on his laptop. It looks boring as hell. I'd rather just play World of Warcraft, which I did... years ago.
The character designs were true to the lore of the game, but something seemed "odd" about one or two of the characters in your movie, mainly the red orc (Hellscream?).
He had a weird shaped head.
The animation and video quality was good.
It had its funny moments.
