This is a series begged to be watched in one sitting. Feature length would have worked better. Unlike comparisons to Santa Clarita Diet, the 'supernatural' is metaphoric of grief, mental illness and love. Viewed through this prism, it is a beautiful tale. Yes, many small tweaks could be made but, arguably, it's those imperfections which add to the power of the argument. Make it through the first 3 episodes and you will be reimbursed with its finale.
