I hated the new effects when I first seen them too. And the second time. And the third. And the fourth. They started to grow on me after that.
Although I do agree the original effects are definitely more authentic. I'm one of those people who thinks good model-work will always trump CG. And for all the criticisms it receives these days, for it's time
TOS had some truly exceptional model shots, especially for what was a relatively modest television budget.
