I guess I don't know what we mean by "hit" then. I tried to address it from cultural impact, box office earnings, and movie quality. On any one of those criteria I don't think it's been that long since Disney has had a hit. If a film needs to push "Frozen" numbers to be a hit, then I'll concede they haven't had one in years.

I think generally people consider a movie to be a hit if it 1. is profitable (they immediately talk about a sequel) and 2. if it does better than expected.

The second part is the problem - if Pixar releases a movie that is good, more than recoups costs, and otherwise is a fine addition to Dreamworks lineup, it could still be considered a complete flop by most everyone.

E.g., "The Good Dinosaur" which (apparently) eventually made enough that it was "worthwhile" - didn't break any records and didn't really make money, so it's a flop (Onward even more so).

It's complicated even more by a movie being able to be a flop, cult classic, and widely loved at the same time.
