Okay, I honestly don't know what this anime is called, what it's about, or if it's even a series or a movie. I just remember seeing part of it when I was really young on the SIFI channel (back when they showed anime every monday).
From what I remeber, a doctor turned into a monster and goes around killing people in the building he is in. A lady runs outside to get help and meets a man in a vehicle. The guy gets out and confronts the doctor/monster. He does some magic gun thing and kills it.
That's all I remember. I don't know if this show is any good or not, but I just want an answer as to what it is called. I would greatly appreciate it.
