Yeah, I'm sorry, but I'm going to have to call you out for not knowing what you're talking about, or at the very least, not explaining your gripe very well.
They shot a tonne of the scenes in Imax so that it is more immersive in certain scenes. The 3D blu-ray retains that (much like the Walmart "Big Screen Edition" of ROTF did). The 2D doesn't.
It has nothing to do with the director (and what the heck is a blu-ray director? you mean the blu-ray producer? No.) not being able to make up their mind and has EVERYTHING to do with a director knowing EXACTLY what they want.
Now, whether the film is shite is another debate (and one best left to another thread), but dude, you're completely wrong. Whether, in your opinion, you find it distracting, is another thing entirely.
