Like @CygnusX1 , I’ve watched up to Episode 2 and have found it a complete joy. The problem solving for the first two episodes was inventive and I loved the character development: we learn more about Doctor Smith, who while still an evil psychopath is becoming more multidimensional. I’ve been a fan of Parker Posey since the movie, Waiting for Guffman, and this role plays to her strengths as an actor.
Lost in Space has always been a visual treat but, unlike series such as The Expanse that relies on special effects over competent acting, there’s a greater focus on story and character.
I will of course be disappointed if it fails to live up to the expectations created by season one and the first couple episodes of season two. But so far so good.
