Back in the day, identifying a movie's villain was as easy as reviewing the official list of Common Characteristics of Cinematic Baddies. For instance:
Scars?
Evil.
Hockey mask?
Evil.
Mustache? Oh yeah, definitely evil.
But with "Let Me In," the scaretastic remake of the brilliant Swedish film "Let the Right One In," premiering today, we've gotta admit that evil looks a little different these days. Case in point: The film stars adorable, angel-faced Chloe Moretz as the girl next door...who also happens to be a bloodthirsty, murderous vampire. But she's so cute! That face! Awwwwww. You know what, Chloe, we'll just give you our blood, okay?
So today, in honor of "Let Me In" and huggable hellhounds everywhere, we've compiled a list of our favorite Evil Sweethearts from Cinematic History. It's evil with a pretty face. Evil with big, shiny eyes. Evil so adorable that when it follows you home, you'll ask your mom if you can keep it.

1. "Jennifer's Body," Jennifer Check
Yeah, yeah, she's a demonic murderer with a taste for human flesh and a penchant for puking up person parts all over the just-washed linoleum. But she's really pretty.

2. "The Ring," Samara
She's a little waterlogged, but Samara is still the most lovable little girl...that is, until she fills your mind with death dreams, crawls out of your television and hides your melt-faced corpse in a coat closet.

3. "The Bad Seed," Rhoda Penmark
We're reaching way back for this one—to the days when children turned murderous over losing a penmanship contest. (Do they even have those anymore?) But little pigtailed Rhoda deserves her due as the originator of the "evil child" meme, because let's face it, she still completely freaks us out.

4. "Village of the Damned," Towheaded Tots of Alien Doom
Most aliens are simple, fun-loving folk who just want to probe your rectum and call it a day. These adorable extra-terrestrials, on the other hand, leap right into the wombs of unsuspecting women in order to infiltrate the community from birth, with the goal of...well, actually, it's unclear. But they sure are cute when they're forcing you to eviscerate yourself with a scalpel!

5. The Good Son: Henry
In an attempt to break free of his feel-good kiddie movie persona, Macaulay Culkin took on the role of Henry—a precocious, baby-faced 10-year-old whose favorite pastimes include skating, archery and throwing homemade mannequins into traffic so he can watch the cars crash and explode. Aww!
