While I enjoyed it enough to put in ~250 hrs to beat The Journey and The Answer, there is just too much stuff in it that would completely turn off a large chunk of people:
Virtually zero exploration
Game over upon leader being knocked unconscious (even though there is a story-based explanation of this, at a certain point it no longer should apply, plus it never applies in The Answer)
Social Link aspect (and pretty much the entire High School portion of the game)
Awful party management
Inability to change equipment in-battle
Time flow (how you're limited as to what you can accomplish in a single day)
Horrible AI of your party
Very low level of difficulty
