Well, I'll give a topic a try!
Overall I very much enjoyed Persona 5 and give it a 8.5/10. However, after I finally finished it after 100-some hours, I realized it was almost want I wanted, but not exactly. I'd probably say the main issue for me was replayability.
The long loading times for and after battles, the slow daily loading screens, and the absence of Haru until later in the game. Idk if it was just me, but watching Mr. Main Character running in circles after every battle while a random teammate kneels (I still don't understand why they do that) was painfully boring after 100 times or so.
I also felt that Haru got the short end of the stick cast wise. Apparently Hifumi was mean to even be in the game, and Haru was added in as a last ditch effort to "give Westerners something to relate to" (according to a dev article I read that I can't seem to find) and Hifumi was scrapped entirely to save time. At least in Persona 3 and 4, the late game characters were in some way related to the story. Haru didn't seem to add anything at all to the story. They called her the "Polar Opposite of Mitsuru", and I was excited to see how she was presented. In the end, she was hardly presented at all.
Still I really loved Persona 5. It was undeniably an JRPG masterpiece that was polished to a gleaming shine, and definitely one of the best JRPGs I've played in a long time. I enjoyed the huge twist at the end, the characters (apart from one of them...), the graphics, the music, and the setting a lot.
