I mean a success for them commercially. I enjoyed it but I did grind my teeth at some of the apocryphal stuff, which was clearly from the JJ Abrams playbook. All the show needed was for a couple of Trek experts to edit the scripts. There are definitely plot holes and technological faux pas that are annoying. They do seem sloppier than the nineties. I don't object to the concept of spore drive, I object to it being so magically powerful that it inconceivable it went away in later Trek.
Picard is better but I get frustrated that at no point do they ever reconcile the existence of three other planets with intelligent androids from TOS and intelligent machines from TNG. Trek is at its worst when it features fire and forget technology of the week. There are some plot reveals that are a bit questionable too and Elnor's tendency to murder people without considering incapacitating them is a bit unsavoury even if he is so adorable. That said, it weaves the lore of earlier shows into the story brilliantly and is very watchable. If they adopt a similar respect for the show's history in Strange New Worlds and edge back more towards the classic formula, I think that will also be successful.
