I will give it a four, just because we miss some of the characters' development (which will be obviously lengthy and unfit for a movie, maybe).
The movie is wholesome, and explain the title a loooot. Forget Rita Skeeter's writing about Dumbledore family, guys! These are the true truths.
The special effects and their magical prowess are on another level.
Jude Law and Mads Mikkelsen are up to their level as well, their acting are just *chef's kiss*. You can see their closeness, yet their distance. Their love and their hatred thru their eyes, purse of their lips, the frown.
Once I see Mads as Grindelwald, I cannot unsee it 😳
