The vocal delivery is fitting for the film and theme, however Christina vocal has not been pleasant to listen to consistently for a while. Save for downtempo numbers and ballads where she exercises control - I hate to say it, but she just screams and strains way too much for it to have replay value.

Songs like PIPE, Like I Do, are the correct vocal key and Unless It‘s With You (with the correct level of vocal restraint with progression towards the climax on the song) are the sweet spot where her voice sounds pleasant to listen to.

Otherwise - No. just no.
