So generally i avoid watching any movie in 3d, mainly because it's a waste of money and the movie isn't made for 3D.
I can't find anything specific for Warcraft but is it made for 3D?
The last movie I watched in 3D that I enjoyed was probably avatar ( not the air bender one, screw m.night for ruining that series). Since then I've only seen a few which were a complete waste of money.
