Interesting. My top five seasons would be the same as yours, but in a different order. My bottom five would be quite different with only the first two seasons of TNG being common. Though I really like Enterprise I am much more critical of some episodes you gave high marks to. Chosen Realm, Hatchery and Daedalus would have an average of 2 in my rankings. You gave them an average of 8.76. Episodes like that is why I give the edge to DS9.
