What is the movie The Fabelmans about?

The Fabelmans is a semi-autobiographical coming-of-age movie by Stephen Spielberg about a young filmmaker growing up in a somewhat unstable household.  His father doesn't understand or appreciate his passion for film, and his mother begins to wander away from the family.  Adding to the strain are the several relocations in order to support the father's career.  The film garnered a rating of 92% on Rotten Tomatoes, so it is worth a watch.
