Steins;Gate ending was awesome, and it's optimism was fine in my opinion because of how despairing the episodes leading up to it were, had its cake and ate it too. Besides, if you want a less optimistic ending, 22 is a completely valid ending by itself.ZehMadScientist said:I really liked how Steins;Gate ended, even if it was a little too optimistic.
Also, the conclusion of Higurashi no Naku Koro Ni has left me satisfied for quite some time.
Puella Magi Modoka Magica... Because Puella Magi Modoka Magica.
I'll edit when I remember more of 'em.
So yeah, Steins;Gate - the ending is the only time I have ever wept in happiness.
Puella Magi Madoka Magica/Mahou Shoujo Madoka Magica also was great. Yuki Kajiura's music playing in the scene with Madoka and Homura was amazing.
C The Money of Soul and Possibility Control - Not necessarily the ending, but the entire last episode was astoundingly good. I have never been so enthralled by economics before.
