i agree with part of your interpretation. i disagree with the fact that you call it depressing. although at first i thought it was about neil wanting a simple life and abandoning the glamorous one but then taking a bitter turn and staying in the "motion picture" world, i now don't think so. he mentions motion pictures as a home away from home which "brings smiles to eyes" (in the last verse he is regarding to a motion picture of himself). well the original motion picture brings smiles to people's eyes but has a hidden purpose which is glamour and greed. at the end, instead of running away from this world, neil instead decides to take it head on, fighting it with its own style. while on the outside he is making himself seem "pretty" to the motion picture world, he is actually destroying it as a hidden purpose. that is his motion picture
