1. What kind of favorite movies do you like?

Question

2. What kind of favorite movie do you like?

- I like horror movies.

(Are the questions and answer correct? Do we have to use the plural form, 'kinds'?)

3. What is your favorite kind of movies/movie?

- 4. It is horror movies.
- 5. It is horror movie.
- 6. It is a horror movie.
(Which answer is right?)

Answer 1

Yes, kinds of movies

Preferable would be, I like horror movies.

I like a horror movie

Of those, 6 would be the best.

Answer 2

1 and 2 are awkward. Either remove the word "favorite" or write the sentence like this:

What kinds of movies are your favorites?
