Don't know why the critics are calling it bad. I enjoy every bit of it. With superb special effects and a very good story, it kept me involved throughout. The acting was amazing and the kind of humour used was also delightful. It's not a Harry Potter movie. But it created a kind of base for the upcoming movies in the Fantastic Beasts franchise.
I would recommend to ignore the critics and watch it. Its worthy....
