1. Sequels: This is the most common term for movies that continue the story of a previous film. Hindi cinema has a rich tradition of sequels, often featuring the same cast and director.
2. "Part 2" in the title: Sometimes, a sequel will be explicitly labeled as "Part 2" in its title, for example, "Golmaal Returns" (Part 2 of "Golmaal").
3. "Series" or "Franchise": When there are multiple sequels, they are often referred to as a series or franchise, like the "Housefull" series.
4. Specific Subgenres: Some sequels might fall under a specific subgenre, like "rom-com sequel" or "action sequel", which could further define their style.
5. "Continuation" or "Follow-up": These terms are more general and can refer to any film that continues the story of a previous one, regardless of its style.
It's important to remember that there's no single "style" specific to second-part Hindi movies. They can vary greatly in their tone, themes, and even genres.
If you can provide more context or examples of the kind of movies you're thinking about, I can give you a more precise answer.
