Quality entertainment right until the last scene
The final scene, where the dog was returned to it's owner, was enough to destroy the effect.
As a dog lover, and someone who can identify with a loser who "watches war documentaries" I found this actually more than just entertainment, but an absorbing character exploration, that was also great fun to watch.
Solo had finally met the woman who matched his awkward exterior with some actual substance. They had a ready made family with a shy kid of a different species that they both loved.
There are those once in a lifetime matches, that are not simply thrown away because it seems more interesting.
Sometimes there is a choice between wish fulfillment, the old Hollywood ending, and avoiding it out of some hope that it will avoid being a cliche. No. It's actually a greater cliche of trying to avoid giving the audience the "happy ending" that we had expected, and hoped for.
And in this case it would have fit perfectly.
