Retool/Playing With

Basic Trope: The format of a show is changed to appeal to new viewers.

Straight: Alice and Bob, a struggling sitcom with some noticeable dramatic elements, is slowly turned into a balls-to-the-wall comedy.
Exaggerated: Alice and Bob, a struggling dramatic series, is turned into an almost Dadaist comedy in the span of one episode.
Justified: Viewers came for the comedy but didn't stay for the drama.
Inverted: Alice and Bob, a show enjoying the peak of its popularity, is suddenly changed for little to no good reason.
Subverted: The shift was temporary. A couple years later, it's back to its old self again.
Double Subverted: But that shift back was temporary, too.
Parodied: The producers change everything about the show, including the title and the main characters - to the point where anyone wonders if it's the same show anymore.
Deconstructed: The Retool doesn't pay off: not only do the fans of the show stop tuning in, but the new premise fails to draw any new viewers.
Reconstructed: The Retool pays off and gets new viewers in the door.
Zig Zagged: Some elements of the show are gone for good, but others eventually see their way to returning.
Averted: No changes are made.
Enforced: "Ratings are down for this show. Let's change it from a dramatic sitcom to a straight-up sitcom!"
Lampshaded: "Remember when you used to be serious?" "I don't think about that, and neither should you."
Invoked: See "Enforced".
Defied: The producers decide that even though they may need new fans, they don't want to upset the fans they already have.
Discussed: "Didn't our lives seem a lot more serious until a few months ago?" "Now that you mention it..."
Conversed: ???
