This is a legendary story. It's been parodied by every animated sitcom that I can think of aside from South Park. In order to make a bad adaptation of this story, the director would need to make a lot of bad decisions. Joe Wright managed to make almost every bad decision imaginable.
I did like Peter Dinklage as Cyrano and most of the supporting cast while the singing was rather hit or miss. When they missed, they missed badly.
The song lyrics could have be written by a seventh grade me when I had a massive crush on a girl in my class while being socially awkward. There's no profound poetry here and that's rather important to the story.
I love Seamus McGarvey as a cinematographer; but, somebody needs to take digital cameras away from him. This movie looked almost as flat as the first Avengers move.
If you're in the mood for a musical, see West Side Story if you haven't seen it yet. Even if you have seen it, a rewatch of West Side Story or La La Land would be more rewarding than this movie.
