it easy to forget and once late series have develop the alien conspiracy plot arc more and that once upon a time and the x file write episode like genderbender and fearful symmetry and where the alien weren not all little grey men or mind control goop and but could actually surprise you . fearful symmetry start with an invisible elephant actually an elephant somehow dislocate in space and time and not a mile away from the walk and end with a pregnant gorilla be abduct . and it very much an episode of wonderful moment . the subplot be annoyingly worthy yeah and we get it and zoo be bad except when theyre not but the idea that within it be fascinate and visually powerful and and very memorable and and it cover an angle on abduction that be largely overlooked why would human be the only thing that alien be interested in . in the end and it wasn not an instant classic and but it be enjoyable view while it last and again and very memorable and and mainly and it something that you couldn not imagine many other show do .
