In other words: "I hate black bars. They should make them go away. Full screen forever!!!"
The aspect ratio argument for 3D is absolutely no different than the aspect ratio argument for 2D. It's an artistic decision at the control of the filmmakers. As the YouTube video linked above clearly shows, How to Train Your Dragon was composed during production with 2.35:1 in mind. That the studio also rendered a "full screen" version for some venues/mediums doesn't change the compositional OAR. The majority of 2.35:1 live action movies are also photographed with extra picture above and below the frame line on the negative. That doesn't make their OAR 4:3 or 16:9.
