Watch Assassination Classroom for free?

I would have a question, namely that the Assassinaton Classroom film will run on Netflix in a few days but I haven't finished the series yet and by then I won't be able to finish the series so someone knows where I got the film Can watch for free (sub or dub doesn't matter)? I would be really happy

If you need an English sub, feel free to use the Animeflix.io page.
