Idiom: in other words; used as an adverb
Movie Review: The dialogue sounds so fake, and the acting is so unrealistic, the audience laughed when they were supposed to cry. Meanwhile, the story itself is pretty uninteresting, and the second half is so boring, the person sitting in front of me fell asleep and starting snoring. I couldn't wait for the movie to end, and I almost walked out in the middle. In other words, you should not see this movie.
