It is watchable. About it I'd say.
Not proper 'old school' style ST but sometimes gets near it.
Discovery is obsessed with the character Michael Burnham which to me is very detrimental to the show and other characters.
(Michael being a woman by the way). It gets very complicated with ongoing sub plots and dipping in for one episode is not really possible like you could with The Original Series or TNG or DS9 or Voyager to a point.
If you liked the 'old school' Star Trek then checkout out the unofficial Star Trek Continues which is on You Tube.
If you are ok with Star Trek not being totally true to its roots and sometimes coming across as Guardians of the Galaxy type sci-fi then watch Discovery & make your own mind up.
