- All Animation Is Disney: Or, in this case, "All Limited Animation is Hanna-Barbera." This always hit Ruby-Spears hard as, after all, both men met at Hanna-Barbera and when Joe and Ken split from them, it wasn't a negative departure. Their shows still resembled Hanna-Barbera shows and shared plenty of voice talent and other employees. Then they became sister studios and worked together. Then the Ruby-Spears library was sold into the Hanna-Barbera library, blurring the line more and more.
- It was once joked that you could put a Hanna-Barbera logo on a Ruby-Spears cartoon and most people wouldn't be able to tell the difference. Which was ironic, as several Ruby-Spears DVDs do in fact just that. But while this is frustrating from a historical perspective, a lot of Hanna-Barbera fans are also Ruby-Spears fans. So while there is some irritation, there's not as much animosity on the characters of both companies being like step-brothers.
- Critical Dissonance: Like the studio it spawned from, critical circles never much liked Ruby-Spears. However, that hasn't stopped many fans from loving their work to this day.
- Silent Majority: On two levels. On one, the name Ruby-Spears is not a highly mentioned named entity but that is also because a lot of people have accepted them into the Hanna-Barbera name (either because of the lawyers or by just plain confusion). So while you might not hear much praise for Ruby-Spears as a whole, there's plenty of love for their shows.
- On the other level, Ruby-Spears is also included in the example on the Hanna-Barbera page. During the time the HB (and by proxy RS) name was more visibly hated on, Ruby-Spears DVD releases have still been in decent high numbers within the already high HB numbers. It is generally unlikely Ruby-Spears would have a solid, if not large, audience supporting them. While they may appear silent, they do exist.
- What Do You Mean, It Wasn't Made on Drugs?: Some of their more...outlandish...concepts. In particular, Rubik, the Amazing Cube; Wild West C.O.W.-Boys of Moo Mesa, and Turbo Teen make one question the sanity of the studio staff.
- It should be noted that Moo Mesa was originated at another studio. Ruby-Spears just continued it; the two others are all on them.
YMMV / Ruby-Spears
