The trip to Neptune, with Roy's constant, Oprahist-self-flagellating narration, takes too much screen time with too little screen time spent on the central problems set up by the script: what to do about Space Kurtz Dad and his Magic Earth Destroying Machine and his Bad Daddy to emotionally damaged son Roy, um, issues. Turns out NONE of these plot drivers need amount to anything. Just an atom bomb and a jet pack. Alternately logical and credible and contrived--Roy can break into a rocket during its launch from beneath said rocket via an under Mars lake. Also, Tommy Lee is young, old, huh, what, randomly looking older in 30-year old vids than when we meet his character during the last 20 minutes. Roy n Dad together must have killed how many? And Roy appears not to have gotten even a wrist slap at journey's end. I was never bored, loved the musical score and soundscape, acting was very good, Liv Tyler was wasted on a near-vanishing character ... disappointing payoff makes for an overblown story.
