Disney Channel's Girl Meets World is appropriately called a spin-off of ABC's 1990s hit Boy Meets World. However, there are some seemingly unique aspects:
- Is it not a "typical" spin-off. Examples like NCIS from JAG or Laverne and Shirley from Happy Days. Characters that are friends, family, or in some way intersected with the parent, but otherwise a unique series.
- It is not a re-boot. An example is Hawaii Five-O. The new version re-uses the same concept and some character names, but that's all.
- It is not a "next generation." Star Trek, Degrassi, Saved By the Bell (The New Class) for example. A future time from the parent, but with all new characters and stories.
- It is not a re-union special. Anyone remember the Brady wedding?
In other spin-offs, characters from the parent series are either absent or at most make occasional cameo guest appearances. With Girl Meets World there are at least two characters- Cory and Topanga- who play an integral role, and many others- Shawn and Eric in particular- have regular recurring parts.
Has any other series ever done anything close?
