I wish they had given it at least a twist at the end, with this level of production it could have been a real hit...
Have all the soppy cringe boring done to death "awww, me family" stuff just like they did, so we get invested at least a little bit, and then at the very end after dad gets home, cut to orbit to mothership, and GLASS THE PLANET!
Then show the aliens warping away towards the little red dot of Mars!
Cut to black, end credits.
Or, they could just digitize the whole.planet if you wanna keep the tone of the movie consistent. More spooky that way I guess, less of an impact, more predictable though
