I honestly think season three is one of the best overall seasons of any Trek series. It’s got good energy, and I’ve talked pretty extensively about why I think the ending is pretty great, actually.

killing Book’s family was kind of idiotic

The poor species was doomed once they were revealed to be spore drive-compatible. They were never going to take away the lead ship’s unique feature.

Also, background character development feels a bit weak.

I’ve probably talked about this before as well, but I think Disco was pretty experimental with the extended cast - they essentially gave what would have been wordless extras on other shows and gave them a bit more to do.

Ultimately, I think it was a bit of a failed experiment, but at least some talented Canadian actors were able to pad their resumes.
