Poorly written comic-reliefs

A Comic Relief is the inclusion of a humorous character, scene, or witty dialogue in an otherwise serious work, often to relieve tension. Comic relief usually means a releasing of emotional or other tension resulting from a comic episode interposed in the midst of serious or tragic elements in a drama. Comic relief often takes the form of a bumbling, wisecracking sidekick of the hero or villain in a work of fiction. A sidekick used for comic relief will usually comment on the absurdity of the hero's situation and make comments that would be inappropriate for a character who is to be taken seriously. Other characters may use comic relief as a means to irritate others or keep themselves confident.

Some Comic Reliefs can be done right and when executed to perfection, some of them can become fan favorites on the show. Take Roger from American Dad!, he is a done right version of a Comic relief, and he has become a fan favorite on the show. However, in a TV Show or a Movie, sometimes, Comic Reliefs can be considered pointless to the show or movie. Such as Jar Jar Binks from Star Wars, he served no purpose on the show, and he has received tons of negative feedback from fans of the franchise.

Most comic relief characters however are incapable of being the main stars of their own show or movies (unless that they are done right), and comic relief spin-offs like mh:terribletvshows:Planet Sheen learnt that the hard way.
