‘Thor: Love and Thunder’ doesn’t rekindle the spark that ‘Ragnarok’ ignited

The impressive mix of tones and styles that director Taika Waititi pulled off in “Thor: Ragnarok” largely fizzles in “Thor: Love and Thunder,” which isn’t as funny as it wants to be, as stirring as it needs to be or romantic as it ought to be. Although well paced at just under two hours, instead of the hoped-for fireworks this comes a little too close to feeling like a post-Fourth of July dud.
