10/10 as a fan but I acknowledge the padded areas and quite weak side quests.
I hate that Zack is alive, hello Mr. Nomura there is no reason to do KH story bullshit here some people should just stay dead and Zack is one of them. Zack is popular due to Crisis Core but he needs to die for Cloud to happens. I only see this as Square Enix trying to cash in on popularity for future spin off.
If Zack is still alive he better be in a separate dimension not in the main Remake timeline.
I was genuinely confused and couldn't figure out whether it was in the same world or vision... Either way I'm not a fan of fan serving getting in the way of authenticity.
