It is still essentially a passive activity while a video game requires considerably more audience participation to move a story or events forward.

Interactivity with a movie is voluntary. If the participant chooses not to use an interactive feature there is no detrimental effect. You can still watch the film. Video game inteactivity is mandatory. No audience participation means no progression.

That is why, to me, interactive features are not a good excuse for higher prices on BD discs. Interactivity does not add any particular value to the act of watching a movie, so why pay more for it? In fact, from some of the complaints I have read, interactivity during a film actual reduces the enjoyment of watching a film because a person is taken out of the film by the need to perform some action for little actual gain.

The biggest strength of movies is passive participation. A well made movie with a good story causes a person to fully invest in the experience. The participant gets fully absorbed into the experience and can even lose track of time while watching. In that environment, "interactivity" is a bad thing.
