this is my general impression too, the origins of the practice is kinda bunk and it's probably not worth the risk for a lot of people. I particularly dislike that a lot of people will see a chiropractor for pain before they'll consider seeing a PT.
that being said, there are individual chiros out there that do good work. The main person I go to for non-chiro bodywork, who really knows her shit, sees a chiro herself and highly credits them for her recovery from pretty severe spinal issues. I'd probably see one only if I was referred from someone I trust.
but generally speaking there's other alternative therapies I'd recommend over seeing just any random chiro. Acupuncture can be a game changer, and is starting to become less "alternative" as some PTs offer "dry needling" now. Craniosacral work can be great for some too, it's a very gentle form of bodywork that can have a big impact nonetheless. Both of those are a lot less focused on manual adjustment, lowering the risk significantly.
