Well, everything's in the title itself, you watch it only to confirm.
I don't want to be so negative like the film critics, but this is a big disappointment for me watching being a film fanatic. I don't think anyone who loved 'Harry Potter' film series would thumb this new beginning. This is not like 'The Lord of the Rings' and 'The Hobbit' from the same universe, but different trilogies. I was excited for something like that, as a concept wise, for the fresh tale from from the fresh characters in the same universe. I don't know about the book version, but the film did not click for me.
It had a bunch of nice characters, and to set in the Harry Potter universe, really it should have been a masterpiece. The major drawback was the story. There's nothing to appreciate the screenplay. It's about some creatures from the magical world got out in the human world, just like 'Jumanji'. So our hero struggles to recapture them. Meanwhile, some others too involved in and the reason will be revealed in the final stage.
Nice casting and great visuals. I won't point out its director's fault, because he has done his duty very well. He's also will be the man behind the rest of the sequels. I think it deserved the Oscars for the costume design. Not a bad film, particularly for the kids. Comparing it with the Harry Potter franchise makes it a worst film, but independently it is an okay film. So the initiation was average, but I'm still expecting the follow ups to be much better.
