what do people think of James Cameron's big budget films? does he waste money या are the big budgets put to good use?

After watching some of his films bigger budget movies, आप think that £200 million is a ridiculous amount of money to spend on a film, but when आप watch अवतार for example its stunning visual effects clearly दिखाना where the money went! his films are enjoyed द्वारा millions across the world so i think his big budgets garantee him a big profit and also can be enjoyed द्वारा us to!
