It did nice at the box office, received mostly positive reviews, was nominated for 2 Oscars and won 1 of them (best original song). From 1998 to 2007, it was the highest grossing traditionally animated non-Disney film.

I've noticed it gets a lot of love on various social media sites from animated movie lovers for its animation, soundtrack, and the way it went about doing characterization. It's maintained a good level of adoration.

So I'd consider it popular enough!

I agree. Such an underrated gem. Rewatched it tonight on 4K BLU-RAY (Yes, Universal and DreamWorks put out a new released transferred from a new remaster of the original 35mm camera negative) and this film, 25 years later, still holds up and is a total banger. The animation, a-list cast, the score, the musical numbers - complete perfection.
