The relations between are very similar; art style, sounds and visuals etc, some say it is a continuation but you shouldn't see it that way. Shinkai felt as though Your Name wasn't a finished masterpiece yet it was too late to change anything, although being a hit of 2016. Given the time needed/wanted, Weathering with you is a different story of its own kind and deserves to be so, watching through comparing it to other titles from Shinkai or A Silent Voice is a mistake from the viewer. Give the film a shot and be in for a surprise!
