A not-bad, not-good, just OK romantic comedy from Amazon Prime. Because we were in the mood for this sort of thing.
Winona Ryder and Keanu Reeves play (respectively) Lindsay and Frank, who meet at the boarding gate for a puddle-jumping plane that will take them up to San Luis Obispo for a … well, you see the title up there? That.
They immediately take a dislike to each other, which means they will eventually get romantically entangled. He is the groom's brother, and they do not get along; she is the groom's ex-fiancée, and they broke up contentiously. Most everyone else is having a good time, but Lindsay and Frank unite in their general distaste for the proceedings.
The trick to the movie (quoting IMDB trivia):
Winona Ryder (Lindsay) and Keanu Reeves (Frank) hold the only on-screen speaking roles in the movie. Movies playing on the TV in their rooms and announcements made over PA systems are the only other voices heard.
So here's the thing: the movie entirely relies on the Lindsay/Frank dialog being funny and clever. But that's a hit and miss thing. Also a "how long can this go on" thing.
