Good analyse. I had the same experience. I was tired of the game before the end. And never had the patience to follow step by step the existing walkthroughs.
One of the problem of the games based on real actors is they get the constraint of the content the developer find on the Internet. Added to the constraint of the developer's imagination (or lack of imagination) stories are globaly uninspired.
You have to make a precise choice in your answer at a specific scene. If I remember well, there is a walkthough available in F95 that explains what to do.
