It's not as good as I remember but a solid entry nonetheless. Origins has both good and bad but let's start with the good:

The game features easily some of the best boss fights in the series (e.g. Deathstroke, Bane) and manages to keep the good old arkham gameplay formula we're all accustomed to while still adding new gadgets to make it feel fresh, unfortunately however these new additions fall kind of flat and their entire justification for existing in the first place is so the game doesn't feel like a straight up clone. I thoroughly enjoyed the direction they took to showcase a much more brutal and younger Batman. I'd say they did the "Origins" part of the game right.

Now, for the bad, the open world is by far the most stale part of Arkham Origins, there is nothing to it, nothing that sets it apart from the other games, it's soulless. The side missions are also incredibly lacking, I never felt the initiative to pursue them. My experience with the game was also surprisingly bad, I encountered numerous bugs during my playthrough, none of which were game breaking but certainly unexpected given it's almost 10 years old. Origins introduced multiplayer but unfortunately you can't play it anymore since the servers for it shut down back in 2016.

Overall, Arkham Origins feels more like a filler entry than a full blown sequel, for good reason that is. It wasn't developed by Rocksteady so we should give it a pass just for that. It's not bad by any means, just unnecessary.
