Someone from the reddit sub suggested this ending for Beyond the sea and I think it would have been so much better than the one we got :
So David tries to ambush Cliff once Cliff re-enters the spaceship after the coolant check. Fails and a fight breaks out. It gets pretty hairy and they're both going all out.
Cut to Lana back on earth. Going about her day as usual. Cut to back on the spaceship, the insides are a bloddy mess. Winner unclear. Ship goes dark and lights up again to show a link has been made to earth. Back on earth Cliff has returned. Comes out and smiles at Lana. Cut to black. We don't know which cliff. Open ending.
