Step right up, ladies and gentlemen, for a sensational three-ring outer space circus featuring amazing planets, phenomenal creatures, stunning acrobatics and very little believable plot or character development. Star Wars Episode VIII: The Last Jedi (B) is basically Rian Johnson’s Galactic Exposition of 2017, in which the visionary sci-fi writer/director assembles an absolute cavalcade of activity while neglecting the delights the preceding film breathed into a trio of new central characters, a bratty villain and a spherical droid. During its bloated running time, Johnson introduces far-fetched new technologies and powers for his ensemble but requires most of them to tread water until what is expected to be the conclusion of this trilogy when J.J. Abrams retakes the reigns. This middle film’s marvels include a pretty casino planet and at least one intergalactic dogfight with pizzazz, lots of cotton candy for the soul. Misfires involve both old and new characters, who behave with perplexing lack of clarity and continuity; some are done no favors through long periods of separation. There’s a gas shortage that rivals the taxation disputes of the prequels in terms of dramatic inertia and at least one moment of sky walking that defies both gravity and belief. Laws of space and time, be damned! Even for this fantasy space opera, this one hits some bizarro notes. For all its fussy audacity, you may leave this funhouse a bit dizzy and more confused than you should feel for the ride.
