I saw Rogue One in 3D, then in 2D. I preferred the 2D presentation primarily because it was brighter... the 3D did not add much value at all to me.
Good example. Rogue One was filmed with all the standard 2D tricks. The most jarring of those tricks, when seen in 3D, was probably the partial focus scenes: Scenes where there were grand backgrounds but the director wanted you to focus on an actor so a majority of the scene is out of focus. When seen in 3D, it just messes with your eyes and mind.
Long story short, the content creators appear to only know the tricks for 2D filming and use those tricks in 3D films... which is just terrible for everyone. Headaches and eye strain are some of the more obvious indicators. My eyes hurt very badly after seeing both of the most recent Star Wars movies in 3D. Those are 2D creations. In no way should they have been forced into a 3D format.
And this applies to the rest of the supposedly 3D content.
Not quite a side note, but I would like to point out why Avatar succeeded so dramatically whereas the rest of the 3D films flopped HARD.
Avatar did not generally shove things out of the screen at you. There are two notable exceptions and they both worked very well: The "writing" on the computer displays stuck out and the floating AIWA (SP?) representatives floated out. Essentially, Avatar appeared like you were looking inside of a box and could see the 3D aspects of the things inside that box. It was very easy on the eyes and the mind. No translations needed to be performed (except when stuff stuck out, which as I said, was sparingly used).
