This movie might be passable as a rental, but not a box office hit. Note I enjoyed the other movies but this one really let me down.
Mads Mikkelsen is no replacement for Johnny Depp, but he did a okay job. What really brought down the movie is the plot and the errors in the plot. Not to mention they had to make Dumbledore be a lover to Grindelwald which really doesn't fit the story of the books. It's like they had to force that in which made it unusual. Though they did do a decent job on making it more discrete.
I was really rooting for the movie.. But very disappointed with the writers.
My son fell asleep during the beginning of the movie which is really saying something..
