I think, too, that there is a wide range of opinion regarding how realistic Gollum looks on screen. Bethberry describes him as "a cartoon character", and other Downers have similar views. Again, don't want to discount that, but my viewings of the film have never broken the suspension of disbelief in Gollum. Even now that I've watched the BTS documentaries and seen indepth exactly how they brought him to screen, I have never thought he looks the least bit unrealistic or out of place in the film next to Elijah Wood and Sean Astin.
I do think that calling him a cartoon character is a bit disrespectful to the work done by WETA Digital. So is putting him in the same class with Jar-Jar Binks. Gollum revolutionized the world of CG characterization. You may not like the way he was done, but you can't deny it was one of the more spectacular parts of the groundbreaking innovations the film brought along.
