They altered some of the events like minmei already famous and already an idol
The mc is already part of the skull squadron
And they change some of origins like the song that become plot device in the end part of the movie
This movie has lack of characterization since it was a movie and its impossible to tell all the vital points of the series
The good thing in this movie is the animation and the fight scenes even today it was the most beautiful handrawn animation you can find in anime
I recommend watch the series first then watch the retelling movie
