I saw it today. It was good. Since it was written by JKR it melds seamlessly into the Wizarding world we've come to expect. New words to learn: No-maj and MACUSA, but old familiar bowtruckles, and spells cast as naturally as one would expect with no need for explanation.
It is set in 1926 New York. Given the era of Prohibition you had to expect the Wizarding version of a Speakeasy. Think the cantina scene in Star Wars. ;)
It started with a montage of Wizarding newspaper articles. There's no way one can take them all it, but it does give some sense of the world you're about to enter.
Johnny Depp? I didn't expect him in the cast. The inclusion of the character he played leaves this open for more movies.
It was both funny (especially at the beginning) and serious. One character who was killed surprised me.
One of the previews that was shown "The Space Between Us" looks really good.
The first human born on Mars travels to Earth for the first time, experiencing the wonders of the planet through fresh eyes. He embarks on an adventure with a street smart girl to discover how he came to be.
