To be honest, I watched this before I seen the series so forgive me, but I did read the manga and wikipedia.
This 55 minute episode shows Edward reflecting on everything that happened during the anime. It is set before the movie so it is up to there.
Story: It was a sum up of everything that happen during the anime. Although it would win an oscar but it was still good.
Art: The usual FMA art but with more 'sunsets and pastels' as this is (as the title suggests) a reflection.
Sound: I had to give this a ten. It has the J-pop of two of the openings
and also has the orchestra doing the nosglastic ones. The music made a lot of the movie
Character: If you know the characters well, this 'movie' will seriosly make you cry. It briefly shows all the characters' personality.
Enjoyment: I felt satisfying after seeing all this. You get this gutty nosglasia feeling when you seen all their achievements goes by in a flash. It even has some humor parts as well. I was on the verge of tears as they squeezed two funerals in.
Personally, I felt touched by the whole thing as it has orchestral music in the sad part. There are many parts about how Edward felt it was all his fault they ended up like this.
