‘Doctor Strange’ enters the multiverse, in what might be the most insanely Marvel movie yet

“Doctor Strange in the Multiverse of Madness” might be the most insanely Marvel movie ever, for good and ill. Unleashing the infinite possibilities of the multiverse throws open the studio’s toy chest, but the anything-goes aspects of that can be alternately thrilling, disorienting and occasionally, a little silly. All told, this sequel proves highly entertaining, if not quite worthy of the pent-up demand for it.
