Same here. (for the movie.)
As i said that is because physical real world cameras have a focus point. So although things are in 3d you cannot look elsewhere than what the camera focussed on, because everything else is blurred. I believe its technically called dept of field.
And its especially weird as dept of field happens naturally in your eyes aka if you look at something close the things in the distance are blurred, so if you have the field of dept of a camera added to the field of dept your own eye experiences, it will just look weird.
3d games however are rendered and not recorded through a camera and thus per default have no field of dept, meaning that 3d is ideal for games. However some games imitate field of dept to give an idea of how an eye would look at things, RO:HOS tries to do this as well when in ironsight:

And for example disabling that field of depth when using 3d technology is one of things in the list that help with making a game optimal for 3d. As your eyes focus themselves on the distances, and thus if you look in the distance things close by get blurred etc.
Other things that are often wrong is light sources/shadows. Which can often be projected as a flat layer on the screen without dept information and the first person weaponry especially while in ironsight (although realistic, you need to close 1 eye to aim accurately).
Companies like Nvidia, Iz3d and DDD atleast in what they say are willing to work with game developers to embed 3d into the game. Even ATI is going to support shutterglasses and 3d technology, while they were against 3d for a long time. Together with that pretty much all monitor manufactures are going to pop out 3d ready screens this year, shows that 3d is getting a big push in its back.
