Coming from an amazing game, expectations with this one are high, and while it definitely delivers a fun experience, fixes some mistakes from FES, and elevates a couple of characters with 10/10 performances, it unfortunately falls flat in many other regards, some characters got the short end of the stick in regards to their writing and a couple events they're involved on, feeling more like plain exposition than the usual Persona writing that makes you feel more attached to the characters. Another issue would be the artistic direction, leaving much to be desired in comparison with the original 2D animated cutscenes.
Despite all, it's still Persona 3, in my opinion, the best of the Persona games, and it's a very valid remake, definitely a must play if you're interested. It might start slow, but the characters in this game and the events that unfold throughout the journey will stay with you forever.
