Delightfully amusing in its subtle, nuanced performances and staging. Yes, I was thinking about Clueless the whole time.
As someone who doesn't necessarily like Rian Johnson's movies, I was pleasantly surprised with how well executed this one is. I think he is suited to the comedy genre as the jokes were well written, called back at the right times, and timed perfectly (especially the little jabs). His direction of his actors in the comedic moments and the family bickering built the tension is a precise way to lead us into a happy confusion. The wrap up may have been a bit quick and difficult to follow, but if you were paying attention the whole time you basically got the gist.
