There's definitely a split of understanding.
This is the game/film that has been discussed, and envisaged for years.
A film that you truly get to play in...... far more than 'the last of us'.
A world populated by great characterisation, and intrigue.
The graphics take us closer to real life than ever before, but it is the acting that delivers that experience.
The key financial factor (for the future) is going to be replayability.
Without this, you can watch it on Youtube, no different to a movie (why buy the game?)
The discussion of 'open world comparison' is not relevant here, because a movie has a strict sequence, to support the story.
Developers need to concentrate on additional modes..... the obvious being a 'stealth gameplay', but also introducing more variety in how encounters are managed.
However, what is clear is that the truly 'interactive movie' is going to happen within the next decade.
The Order 1886 is almost that movie.
