Obviously don't know where you are but it appears to be on Hulu in the US and Disney+ in Canada and probably most of the rest of the world (where Hulu content usually goes).

But yeah, I echo most of the other comments, it's great. There is an aspect, at least for me, that enjoyed it because everyone was watching it at the same time and it felt like reliving the events of the OJ case on a weekly basis, even if you didn't originally live through it. I wonder if that would be lost on you if you're not aware about the case or since you're binging it on your own years later. But I don't think that really detracts from the performances or the drama of the show.

That being said I would maybe recommend watching the ESPN documentary first as others have suggested, it's really, really, good and goes through the entire case and OJ's live really well.
