Is it worth watching?

Yes, is the short answer. Violet Evergarden is an amazing anime filled with beautiful artwork, soundtracks, tear-jerking moments, and sometimes a good gunfight or two. It's an anime with visually stunning art, that goes from character art, scenery, objects, texture, etc. The art that Kyoto Animation does, is well known for being able to convey the character's emotions perfectly. It makes every scene, 100x better, especially scenes that are made to make you cry, feel sad, etc. We saw that as well in SIlent Voice. But art is not the only thing that it has going for it.
The anime has a lot of characters that I enjoyed, and surprisingly there were none that I hated. Every character is unique and likable, you see why they do the things that they do, later on, either that be bad, or good. A lot of the characters have an episode dedicated to them, at the start they saw Violet in different eyes then at the end, they didn't know why she did the things that did, or why she acted like the way she does, they didn't know the trauma and pain she suffered through. One of my favorites was Benedict.

Violet Evergarden has about 49 soundtracks in total, including the movie, and OVA. All of the soundtracks were amazing to listen to, in each scene, it was either a scenery shot, a somber moment, or a very tense scene, it very much added to those aspects. Amazing work, done by Evan Call.

The whole premise of the story is about Violet, finding herself. After she is picked up by Lt. Colonel she is taken to the company he made after he left the army because she didn’t know what to do after the war, she was used as a “tool” for such a long time that she doesn’t know how to be a normal human being, so she goes to his company, a mailing company. At first, she is given the job of sorting the mail, then delivering it, but after that, she encounters herself with one of the customers of the Auto Memory Doll. She sees how one of the Doll’s does her work, she conveys the feelings of the customer into the paper and relays it back to them, but at one point she conveys the words “I love you” into the paper, Violet is stunned, after that she asks the Colonel to help her be an Doll. She wants to find out the meaning behind the word I love you. She goes to many customers, a lot of them with painful experiences, writing letters to loved ones, or ones who passed. She witnesses many forms of “love”.

This anime made me cry sometimes, it was very good, I enjoyed it, I know it’s a turn off for many people, since the beginning is kinda slow, and others might find it a bit boring. But it pays off to watch it, I enjoyed it and I’m sure you will too ( I hope )
Violet Evergaden 10/10 My opinion you can have yours
