CHANGELING series-Seriously, What is This?

The new series THE CHANGELING now streaming on Apple+ is categorized as a drama.  Of course, this ambiguous genre does little to direct one's expectations.  After having viewed only the first of its eight episodes I'm at a loss for what it's actually about, where it's going and whether to commit more time to watching.  The opening scene is a tempest at sea in the 19th C with a sailboat headed into a tsunami which should assuredly destroy the ship and its passengers.  Miraculously, the ship makes it safely over the gargantuan wave while we watch from underneath the vessel and told it was given help.  Thus we're given to anticipate a supernatural element to the tale.  The story quickly shifts to the 20th C in New York City where parallel love storylines commingle with two comely couples; one being Apollo (Lakeith Stanfield) and Emma (Clark Backo)..  Apollo is the biracial son of handsome pair, Lillian and Brian in 1977.   The persistent appeals from Apollo and his father to get the women they're smitten with on a date mirror each other in charm and tenacity.  Both Emma and Lillian share a resoluteness in refusing their suitors. But, when succumbing to the charms of being wooed, both couples are happily wed.  Apollo's father abandon's the family when he's only four.  We're left not knowing why or where he went but Apollo has repeated nightmares of his father returning to kidnap him.  Emma goes on her long planned trip to Brazil after falling for Apollo and ventures into a forest despite warnings to the contrary.  There she encounters an elderly, unearthly woman.  The woman beckons Emma to her and bestows her three wishes to be granted providing she doesn't cut the string she ties around her wrist.  When she returns Emma shares this with Apollo who assures her that he will make all her wishes come true and cuts the string from her wrist.  There's several eerie twists in this time jumping love saga besides the unresolved, unsinkable ship.  Apollo's nightmare's of his father may be frightening recollections.  Emma's enigmatic encounter in the Amazon  felt menacing.  And, the birth of Emma & Apollo's son occurs au natural (as Emma wanted) aboard a NYC subway when the power turns off.  Delayed metro trains are not rare phenomenons in the city but the timing of their son's arrival is certainly circumspect.  The city and its allure are captured beautifully and the acting is all excellent.  CHANGELING appears to be constantly changing shape reminiscent of Churchill when describing Russia as "a riddle wrapped in a mystery inside an enigma."  Given the show's title and its hints at horror, one better buckle up for the series because it looks like it's going to be a bumpy ride.
