I don't know why people saying this is the worst part of harry potter series! I admit this movie is full of suspense & complicated other than any story . And there is no satisfactory climax. Basically Fantastic Beast is before harry potter series so here rowling is showing the origin of all the characters . Hence the story is becoming more complicated but this is not the finishing , so keeping that in my mind I loved the story. & I wish she will quench everything in next parts.
