as...as / so...as

[Penuel]

Hello, please tell me which of below is correct, or, can both of them be correct?
The movie isn't as interesting as the book / The movie isn't so interesting as the book.

Thanks

Yes, both are OK to use, but the first is the better one to use.

Easier to say, " The book was more interesting than the film.

so....as is used in negative sentences, while as.... as.... is used in affirmative ones.

So, the movie is not so interesting as the book would be grammatically more correct.

[Hello]

Thanks for my great friend ,Bill .and..
Bravo KArmine.

Dear.......Both are right but (so...adj...as) should be used in negative but(as...adj...as) can be used in both negative and affirmative ones......

[Mr Mohamed El Sheashaey]

question? what are the comparative and the supurlative adjective of the adjective (up)? i think it is irregular adjective.

[Mr Mohamed El Sheashaey]

but i think there is difference between as.....as and so......as .i mean as.....as can be used in affirmative & negative sentences but so.....as should be used only in negative ones so don't hesitate and use as.....as to be in the safe side ....Thanks
