The show's fairly good so far, a nice continuation. It maintains the same fairly comical tone as the original, though a bit more in a modern snarky-young-people mode. But it feels pretty authentic, with the original screenwriter Bob Dolman on the staff (credited for episode 2).
The new characters are reasonably effective. Kit and Airk are both a lot like their father Madmartigan in different ways, though Kit has her mother's toughness. (I wish they'd quit mispronouncing Airk as "Eric" all the time. Davis is the only one who seems to get it right, perhaps because it was the name of Gavan O'Herlihy's character in the film.) Elora is appealing; I'm surprised she's blond instead of a redhead, but they handwaved that in episode 2.
Erin Kellyman sure gets around the Disney multiverse, doesn't she? She was Enfys Nest in
Solo and Flag Smasher in the MCU, and now she's in the Willow-verse.
The time frame is weird. Davis and Whalley are both 34 years older than in the movie, but Kit, Airk, and Elora are played by actors in their mid-20s, and their characters seem more like teenagers. Sorsha says it's been 200 moons since Bavmorda's defeat, and if this world's months and years are the same length as Earth's, that would be less than 17 years. Either way, it seems that leadership has aged both Willow and Sorsha disproportionately.
Davis's daughter Annabelle did a good job as Willow's daughter Mims. I'm glad they included the character and let her reunite with Elora, even if it wasn't the same actresses.
I wish they'd been clearer about character names. I assumed the goateed Nelwyn who came along with Willow was Meegosh, his friend from the movie, and I had to do some searching to determine it's a different character named Silas.
About half-way thru the first episode. Visually it looks good, but the choice for 'accents' is kind of strange. Not sure why some people have some and some people sound like they just came off the street in LA when they all are ostensibly supposed to be grown up in this same kingdom.
That's pretty common in fantasy, SF, and historical series, but in this case I think it makes a fair amount of sense. Madmartigan's son and daughter have the same accent he did. Maybe they spent more time with him growing up because Queen Sorsha was busy with affairs of state.
And they said in the episode that Tir Asleen is a haven because of the magical barrier around it, so people come from all over, including Jade's family. In the movie, Tir Asleen was long-abandoned, and Bavmorda had devastated many other kingdoms. So its restored population was probably an eclectic mix of peoples, even before the barrier. Thus, a mix of accents is plausible.
