With the budget of $44 million, it was the most expensive animated film ever made at the time. Earning $21.3 million domestically, it led to a loss for the studio, putting the future of Walt Disney Feature Animation in jeopardy. Due to its poor performance, Disney released the film for the first time on home video in 1998.
Despite growing up in the 1980s, I actually never heard of this Disney film or any of its characters. Even now (2017) when I finally watched it, it seemed like a film that never existed. If Disney tried to bury it, I can understand it being forgotten throughout the 90s, especially as their second golden age was overshadowing decades of duds.
The movie itself is neither good nor bad. A few repeat viewings and it would probably grow on me, but there are no really memorable characters. And there are no songs, which is what really makes a Disney cartoon immortal.
