What You Leave Behind
Alright I took your list and added seasons as a reference.
Using *'s to denote the number of free slots for each season.
Ironically were pretty consistent in our numberings, your about on average leaving out 4.5 episodes per season less than I mentioned.
When you factor in personal favorites I think we can get a list that is quite clear.
