Not all ways.
The worlds are scarce and bland ( Not as bad as days but still bad compared to Kh2 or 1.) The story starts off really slow and arguably bad. And playing the game three times over to get the full story is bull****.
But everything else is near flawless, especially gameplay.

Brawl is like ZSS' breasts. Well rounded for casual players.
