I think BOB exists as a common representation of evil--IMO what we see as the face of Bob is just a use of the medium of film to convey the capacity for evil that we all have.
*************************SPOILERS******************************
I always found Coop's explanation the most satisfying:
Albert: But people saw BOB, people saw him in visions, Laura, Maddy, Sarah Palmer. Harry: Well, I've lived in these old woods most of my life. I've seen some strange things, but this is way off the map. I'm having a hard time believing. Cooper: Is it easier to believe a man could rape and murder his own daughter any more comforting? Harry:...but if he was real and we had him trapped and he got away, where is BOB now?"
As far as existence goes though, what's the deal with the other BL inhabitants? So BOB can "jump" in to other people, Mike can just cruise around through both worlds looking like a OAM, the giant turns in to an old man waiter when he wants to get Coop's attention, and the LMFAP can only be in the lodge. What do folks on the board think about how Lynch/Frost's different use of movement and action for these characters relates to the story telling?
