This is a rather silly thread, truly. Art is art. A great movie does things video games can't, and a great video game does things movies can't. Is either superior to the other? No, they're just different. This is coming from someone studying film and planning to make films for a living - there is no sense of better or worse when comparing these two media.
I'd also argue that people who are voting video games over films on grounds of immersion aren't appreciating films to their fullest extent - most films that I would rank as good (or better) are just as "immersive" as any video game I've played (even though I detest the term "immersive" in the context of art, since immersion shouldn't be the goal).
