Good acting, good special effects and cinematography. The storyline and methodologies of the characters to achieve their goals are often illogical, especially in season 3 with Serac (who is supposed to be this genius who is trying to save the world), he struggles to figure out that charlotte hale is a host and further struggles to kill her or locate Delores. And why do all the humans seem to suffer from stormtrooper fever (99% of their shots miss) also they don't seem to give us any clever/realistic action sequences.
