I am so sorry I missed it. I hope that by making the movie the kid did come to some sort of grip with his father's death. From the videos I've seen of him he took Gene's passing really, really hard. (He seems to be as sensitive as his father was.)
And for that comment about Gene cheating on his wife: if you've ever been in a loveless, or even married for that matter, you'll know that marriage is in the heart and not on a piece of paper. You can be married and fall out of love or not even marry for love in the first place. We don't know what went wrong in the first Roddenberry marriage and we are in no position to judge. We have never heard from Roddenberry's first wife.
Majel a slut....sorry, never gonna believe that one.
