There are some movies that gain something in 3D, like Tron (or Avatar I guess, I saw it in 2D). This isn't one.
movies that gain in 3D, are generally shot with 3D in mind, that's why they gain something. if they had intended this to be 3D, it would've been a totally different experience. scenes with Thor's hammer, or the Destroyer's energy blasts, or the bridge transport could've been so much more if they'd been made with 3D in mind, instead of needlessly tacking it on afterward.
