Well, here is my review coming from someone who knows this stuff and is going into this field.
You all keep mentioning that WETA is real because of the miniatures, but I can tell you that each SW movie probably has as much miniatures as King Kong or LOTR. Not everything is CG. Another thing is the actual subject matter. Everything in LOTR or King Kong is actual real world things that are either changed a little bit or made bigger, which means that you have something to relate it to. But in Star Wars, most of the stuff is not possible to exist at all, so you automatically know it's fake, even if it's actually done in an exactly realistic manner. One thing I have to say for WETA though is that they can do stuff pretty fast, seriously, they had what, 2 years to do the effects for King Kong? King Kong had over 3,000 effects shots (shots involving some sort of CG element) and they completed really fast, that's equal to like 2 hours nonstop of CG effects. One big thing for ILM that it has going for them is their digital matte painting department. Digital Matte paintings are where an artist draws a painting over the video to extend a set or to cover up something, they are actually drawing what is supposed to be there, and it has to look realistic. Nowadays with CG, they can do it in 3D though, they make a 3D model of what they have to paint, render (rendering is where the computer calculates everything to make the final image, shadows, lines, highlights, all that) out a big image of it with shadows calculated where everything is just one color without textures, then they draw over that image to the final look, and then project their image back onto the 3D geometry so that they can do camera moves with it.
Another thing, is that a lot of people from WETA are actually people who used to work for ILM, so the talent has kind of spread. Also, currently, a lot of the new 3D advancements (Like Sub-Surface-Scattering to make realistic skin for characters) were developed by ILM. Besides that, there is a lot of stuff that is done in Star Wars that you don't even notice, but they do it so well it looks natural.
