I tried watching this (I grew up with it remembering it's on TV) and while it's watchable, it's not that enjoyable in modern times because it hasn't aged very well at all in terms of the FX so it's hard to get immersed.

I know if I stick with it, it will probably get good (doctor who was like this for me) but it's a huge slog.

I feel Star Trek TNG lucked out with all the choices they made. The designs and effects generally hold up.
