Can any native speaker tell me whether I should use it, this, or that in the following context?
John: Have you ever seen the movie "Titanic"?
Me: Yes, It/this/that is a great movie.
To me, 'That' sounds the best and there is no place to use this here at all. What do you think, native speakers?
And I am providing one more context to be clearer.
John: Hey subha, I've come to know that you went to a theater to watch "La La Land" last night. How is the movie?
Me: It/that is a great movie, probably the best movie I have ever seen.
