I think the first episode is going to get a lot of views just because of idle curiosity and hate watchers. They might tout that as a success purely based on numbers but views for ensuing episodes will fall off a cliff.
This entire concept is extremely poorly timed. It feels like something they should have released 2 years ago when Meghan was relatively hyped and there was a brief period of optimism coming out of covid. It seems like it was planned for that period but got delayed for whatever reasons. The current zeitgeist is absolutely wrong for a gratuitous lifestyle show about showing off your money and hosting skills. Many "Utah wife influencers" in the same genre have also been phased out of popularity on social media. It's all become too cringe and tactless in a world on the brink of recession and war.
Also not sure why they're releasing a summery Californian aesthetic show in the middle of dreary January. Even if people in the UK, Europe or large swathes of the USA wanted to emulate what she does, how could they even get started right now? Really shitty timing right there.
