I can’t deny that I am still not an adult yet., and

I do think Disney films are awesome.

For an example, the film about sea monsters, Luca.

I can tell that someon people will never accept sea monsters, but some will.

Giulia is one of these kind group of people.

I can’'t deny that I a'm still not an adult yetyoung.

But there are tons of adults that love these films, too.

I think the films are not onlyn't just for kids.

To sound more natural

Giulia is one of the kind group of people.

He has his own ideas, and he can tell the difference between danger and fun.

I a'm not trying to say kids are dumb or stupid.

To sound more natural

This is 'correct' but the double negative is a little confusing - perhaps 'It's true that I am still not an adult.'

For an example, the film about sea monsters, Luca.

I can tell that someone will never accept sea monsters, but some will.

I'm not sure about the word 'accept' here which is a bit unclear - perhaps 'will never like' or 'will never enjoy watching'?

Giulia is one of the kind group of people.

The meaning is a little unclear - 'Giulia is a kind person'? If you let me know what you were trying to convey, I'll give a more helpful correction :)
