Escaflowne---there is symmetry in it, and its the capstone to a Heroic Monomyth type of tale
SAO Season 2---fuck Season 1. Even if Fairy Dance had a good ending, it doesn't redeem being fucking Fairy Dance arc. RAGE! Season 2, though? FEELS!
Star Wars Episodes 4-6---again, classical Heroic Monomyth story with a classical ending
Star Wars Episodes 4, 5, 2, 3, 6 (aka, the Machete Order)---when seen in this viewing order, the Prequels and the Original Trilogy make an even bigger and better Heroic Monomyth! Machete Order is best order!
A Certain Scientific Railgun---big ending battle, capstoning a different kind of story than you see in the first few eps of Railgun. Railgun isn't an epic tale by any means, but the season 1 ending was still quite satisfying.
Lord of the Rings---HEROIC MONOMYTH ENDING
The Hobbit Trilogy---HEROING MONOMYTH ENDING
Fate Zero---Hear me out. If you're NOT a Type Moon fan, then the ending to Fate Zero is IMMENSELY unsatisfying. But those of us who watched/read/played Fate Stay Night gain a sense of completeness and closure with Zero. Now we see the full flower and brutality of the Grail War and how everything between characters, families, and concepts intersect when they fully evolve in Stay Night. Zero was a necessary tale in the Fate storylines, and seeing how things took root, grew, and ended gave much more credence to what was laid out in Stay Night
Sailor Moon---what can I say? the first season had an epic battle against the villainness in a completely different, brutal setting (Arctic Pole), with kickass music, and many heroic sacrifices. shame they had to keep tacking on stupid storylines after it....
Game of Thrones---hahaha, the Red Wedding. ANY ONE of those moments in episode 9 would have sent me to tears. then they kept on going. GOD, the horror! and then episode 10....i didnt know whether to laugh or cry.
