The Harry Potter 20th Anniversary Reunion Special is essentially a long bonus feature youd probably find on a DVD or Blu-ray box set. I wasnt convinced a time or two that old interviews werent just reused.

What Return to Hogwarts captures best, in the end, is how completely life-changing an experience it was to make these films, even for the less-recognizable cast members who also grew up on set.

It is a slick and calculated production, designed to give Potterheads exactly what they want, how they want it. But it contains enough untold stories and honesty from the participants and unfakeable camaraderie to give it more genuine heart.

Harry Potter 20th Anniversary: Return to Hogwarts is an emotional, enlightening, and thrilling retelling of the experience of making the eight films that defined a generation.
