Whoa, whoa... hold up. You're inferring a statement that I didn't make. I never said anything about the VFX in Nemesis. But I suppose I might as well now.
They are perhaps technically superior by virtue of the fact that Nemesis came along nearly a decade after one of the films you're criticizing -- on the shoulders of giants and all that. I was just responding to your opinion that the VFX in Generations and First Contact were, "about the worst work ILM have done." I happen to not share that opinion, hence my examples.
