This is a warning, not a recommendation. Tonight’s plot has the inappropriate aliens of this silly ABC sitcom, along with one of their earthly neighbors, showing up on an episode of ABC’s Shark Tank, requiring the judges of that show to act and react as players in a sitcom, rather than as themselves. It dilutes the brand of the ABC reality series, which follows immediately, without necessarily helping The Neighbors. Disney and ABC are very, very big on corporate and artistic synergy, but this is one of its more insidious recent examples.
