I like that all three movies kind of have their own distinct styles and approaches to what kind of story they were telling.
Two Heroes felt like an extended anime or OVA episode. Production qualities minus the ending being around the same level, focusing on just the core cast, featuring new lore with some fan service, mostly just all around a fun time.
Heroes Rising felt like a manga arc. Production values were increased all around. It has a big grand story with important plot developments thrown in, trying to feature as much on the whole cast as possible, and focusing primarily on the wow factor.
World Heroes' Mission felt like a spinoff chapter. The main focus is primarily on the new character being relatively low-key, with all the big important action just being backdrop to the grounded story. Plus having the best directing of all of them.
