First off -- Scamander's suitcase (which is the reason I put a spoiler warning on this, in case someone would rather see the film without knowing anything at all). When I get this on DVD, I'll probably watch this section over and over -- looking in the corners, trying to peer off-screen. It's a cornucopia of sensory overload -- part sideshow, part impromptu zoo, and wholly engaging. I definitely empathize with the hapless pastry chef, Kowalski, as he staggers into unimaginable vistas and through canvas apertures that turn out to be dimensional engineering portals of which even the Time Lords of Gallifry would be envious.
Next: Scamader's mating display on the ice in Central Park. It was really, really hard to stop laughing at that one -- I was strongly reminded of the ostrich scene in The Gods Must Be Crazy II. So DANG funny, and visceral -- Scamander is the ultimate crypto- zoologist/magicanimalian behaviorist!
Engaging minor characters, a plethora of detail, and the big realization at the end that made me slap my forehead (well, DUH, of COURSE!) -- there's really not a single place in the movie that made it difficult for me to suspend disbelief. Fantastic fun!
It could have been one hot mess -- involved story lines, gigantic milieu to offer and explain, tangled corporate information, complex familial relationships. But the Wachowskis deliver it all up with laser focus, and you never get so snowed in by characters or situations that you lose your way. From the seemingly simple beginning to the equally seemingly simple ending, you are kept to a logical course that allows you to accept some very complex details without a hiccup. The plot line is so focused that the audience accepts willingly the vast implications of the bigger picture.
This was a fun, fun, fun movie -- slick, great chemistry between the cast members, fabulous special effects which never overshadow the heart and soul of the humans at the center of everything.
