I found Jupiter Ascending to be brilliant and refreshing.
Star Wars is a peculiar comparison as Jupiter Ascending is in many ways its polar opposite.
I loved the first Star Wars movie, and the others had their moments. But, Star Wars generally was semi-camp good guys versus bad guys with cute gags and intense action. The characters were iconic. The movies were replete with oohs and ahha and laughs. As a teenage male, I certainly identified with Luke, was captivated by Leah, and was intrigued by Obi Wan. But, I can’t think of a character except Luke who I could relate to as I might to anyone I might actually know or have known.
Jupiter Ascending begins by building characters that I identified with as being like people I know or who I could meet on the street. Mila Kuntis was such a surprise as I only knew her from her role on That Seventies Show where her character was supposed to be mostly one dimensional until later in the series. In Jupiter Ascending, she was seamlessly convincing as a person - a person who might live in a house down the street or in an apartment down the hall. So, when the weird begins and the action starts, she draws you into what the character is experiencing in a way that Star Wars seldom did.
And, I found the world building to be great with enough camp to provide a timely laugh. And, the conflict to me was much more relatable than those in most of the Star Wars movies. It is a movie that I enjoy watching again from time to time.
I would give the movie at least a 90 out of 100 because of the high quality of the acting, the character development and the fresh aspects of the story. As to the criticism of Channing, I think that he and others played the roles that were intended; we are seeing things from the point of view of a person who lives in our neighborhood. This is Jupiter’s story and she encounters huge cultural differences, so there should be culture shock that is overwhelming and leaves many perceptions superficial and only partially understood.
