The Wachowski siblings’ “Jupiter Ascending” is not “The Matrix,” according to the majority of critics panning the science fiction spectacle starring Channing Tatum as an intergalactic bounty hunter and Mila Kunis as the oblivious heir to the universe. The Warner Bros. release has 31 percent “rotten” approval rating from 49 critics counted, so far, by Rotten Tomatoes. Unfortunately, even the 15 reviews the critic aggregator considers “fresh” aren’t very positive.
