Fantastic Beasts: The Crimes of Grindelwald Trailer or Dear Disney this is how to create a cohesive connected story over multiple generations with a clear beginning and conclusion......

The first movie felt very self contained, but after seeing this trailer I'm seeing some very fascinating connective tissue! Are we witnessing the seeds of Voldemort being sewn? Did we just see Nagini?
Who's the woman sitting next to Credence Barebone? Are these two Tom Riddle's Parents? Is this Grindelward's plan to create Voldemort?
How does the legend of the Deathly Hallows fit into this movie.
After seeing this trailer I'm really looking forward to seeing this movie.
Unfortunately my son who absolutely loved the Harry potter films didn't enjoy the first Fantastic Beasts film...he fell asleep.
So it might be a struggle to get him to join me to see this one.
