No, I don't think only well-known directors can make the best movies. Nowadays, many new directors are making a name for themselves with innovative ideas and unique storytelling techniques. Independent films, which often don't have famous directors, regularly receive critical acclaim and awards. Plus, with today's technology, anyone with a good story can make a high-quality film without a huge budget.

Yes, I think well-known directors are often behind the best movies. They have better access to resources, which means they can use the best technology and hire the best actors and crew. Their experience also means they're better at handling the complexities of big productions. Plus, their reputation helps attract investment, which is crucial for making high-quality films.

It really depends on the situation. Some film genres, like big-budget action movies, might benefit from an experienced director's expertise. However, new directors can also make great films if they have a strong vision and the right support. What counts as the "best" movie can vary widely depending on who you ask, as everyone has different tastes.
