Director Taika Waititi’s building blocks for his latest Marvel entry include three parts Airplane! style quips and playful pratfalls, three parts romantic comedy and four parts solemn action. It’s a wonder Thor: Love and Thunder (B-) works as well as it does in spurts even though it doesn’t really hang together in a cohesive way. Chris Hemsworth is amusing and swashbuckling as the central hero, although there’s never any real action stakes as he and colleagues march through perfunctory episodes. This installment is largely about the god of thunder regaining his emotional mojo. Natalie Portman returns as a love interest with new powers and an occasionally resonant backstory; she’s good enough to warrant a bit more. As new villain Gorr The God Butcher, Christian Bale is acting in a whole different universe, menacing and maniacal under macabre prosthetics. There’s also an amusing series of sequences involving a convention of deities. The film is often a clever lark, largely inconsequential and a missed opportunity for even more fearless and frolicking fun. This one doesn’t throw down the gauntlet with quite the precision or focus necessary.
