Super Mario 64 DS was an extremely disgraceful and horrifying mockery of a remake that does not deserve to exist and essentially made fun of the greatest platformer of all time.
Also SM64 needs to have a remake.
Sword Art Online is often revered as an incredibly sad show, with lovable characters dying left and right throughout and the ability to make even the most manly men crumple into tears. I wept not once for it.
This video made me tear up a bit.
