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.
CGI is great. It's a modern marvel. But there are some things it can't do. Yet.
Those original Enterprise flybys made me believe. The remastered stuff looks cartoonish incomparison, in my humble opinion.
There's a reason that the original shooting model is in the NASM. Realism.
Remember the scene in Insurrection where Picard touches the Phoenix. It's tactile, it makes it real. Data didn't understand, but Picard knew. I feel the same way about shooting real models.
