Sonic.exe: To me, it's "so bad, it's good", but is thankfully better thanks to a reboot made by someone with permission from the creator of the original. Either way, the pretenders make it look like a 5-star dish.
Jeff the Killer: I dunno. I mean, it does have an origin, even if it's panned critically nowadays, but the connected one, Jane the Killer, doesn't exactly have an origin about Jane at all. Okay, she wants to kill Jeff to avenge her parents, but there's no explanation for her pitch-black eyes or equally pale face at all, making it seem like a midget in comparison.
