3D movies can enhance the viewing experience by adding depth and immersion to certain scenes, creating a more engaging and visually stimulating experience for the audience. However, some people may find 3D effects to be distracting or unnecessary, viewing them as more of a gimmick than a meaningful enhancement to the film. Ultimately, whether 3D movies enhance the viewing experience or are just a gimmick can vary depending on personal preferences and the quality of the 3D effects in each specific film.
