I know my old man was a huge TOS fan and for years didnt like TNG. But eventually he came around and admitted it was just getting used to new actors, new style, and newer TV methods. From then on DS9 and Voyager worked for him. I feel I went though the same with Discovery. At first I really didnt like it. In a lot of ways I still don't. But after a rewatch I found it a lot better. Just getting used to the new ways. Sure it might have been better to avoid the whole past time line thing and avoid a lot of retconning but that's just how it is.
