“Everything, Everything” movie review

No spoilers in this review.

Everything, Everything is not a brlliant movie. First half is depressing, second half is better. I like the ending.

There is very little dark stuff in the movie so it’s ok to watch.

All in all, I will not watch it again.

Welcome
