Its a failure no matter which way you slice it. If you think of it as a movie, the plotholes and non-sensical story and story-structure break any amount of pacing and narrative because you cant enjoy the story being told, you spend far more time trying to figure out which part of Jodie's life you are experiencing and how whatever is being shown is influenced by past events or how it could affect future events and it effectively does neither at that point since past events are never brought back up, except as throwaway subtle references and no part of the game has any direct effect on anything that follows it.
And as a game it also fails, for the sheer fact that it tries to be non-linear. That killed the story aspect, that killed the experience of living her life, as disjointed it may be. If your story already failed for the reasons stated, then the gameplay has to matter and there is nothing in the gameplay that matters because nothing has any effect, you can not lose the game, you cant fail, your decisions barely mean anything when viewed in the larger picture. There are a few moments where you have a choice, but it boils down to good versus evil decision, a black or white moment. Example, when the kids are mean to jodie, you get the choice to ruin their party, or just leave. And that is all there is, some moments even lack the choice as with the almost-rape in the Bar where you are eventually forced to kill the guys, you can not avoid the almost-rape, or killing them in any way. There is no choice and ultimately no consequence to your actions, the game does not change based on how you play, which could work with the non-linear narrative very well, so again its a failure there.
Gameplay and Story fail on their own merits and neither can save the other, thats why the game is ultimately a failure because it tries to do alot of things at once, without actually doing anything other than trying too hard to be artsy.
