As someone who's a big fan of the manga, I think the Netflix adaptation does a decent job for anyone trying to find more Alice in Borderland content. However, the devil is in the details, and except for the main story arcs, it's quite different from the original story.
Many characters are introduced earlier than expected, and some games have changed concepts entirely. Certain story beats are shuffled around or erased. In addition, Arisu participates in several games that he wasn't part of originally. I would have to say to avid fans of the manga to watch this series pretending you have no prior knowledge unless you like to be disappointed. But by itself, it was spectacular to watch this interpretation of Alice in Borderland.
