The 4 leads have nothing to do here. They could have filmed this movie without them quite frankly. It's basically just 2 hrs of JK Rowling beating the viewer over the head trying to get us to realize how evil Donald Trump is. By the end of the movie, there is a 5-10 min scene where one of the characters has to explain everything to the audience because apparently we're too stupid to understand the complexity of a plot that a 2nd grader could have come up with. But yea, it has awesome special effects so the kiddies will love it. Will any adult with a viable brain like it? I doubt it.
