Sure there's a lot of good things about kingdom hearts 2 but there is bad things about it as well
mine:
Too short{It took me 24 hours without a walkthrough}
All the worlds are way smaller
Lion king's fighting system sucks
No dodge roll....
only one optional boss
no exp in the tournaments
Summons are a waste of time
they made the Sora vs Roxas fight into a cutscene
the 1000 heartless battle was boring and easy
No soft reset
