Who goes there? Someone running late.

Was watching a big playlist of movies over the Halloween weekend with the wife and her family and we got into a conversation of Halloween movies vs. horror/scary movies. There are plenty of movies that fit the theme for Halloween, but they aren't always actually horror or scary movies. It got me thinking a bit, since there aren't a lot of horror movies that I actually enjoy. I'm not an overly huge fan of the horror genre (especially slasher flicks), because too often they rely on people being incredibly stupid for the plot to advance. Thankfully, that is not always the rule, and I had to think of what my favorite scary movies actually are. So here's a pretty comprehensive list of the ones that I really enjoy and in no particular order:

The Thing (1982) - One of the all time great movies in general, and will never get old.
Event Horizon (1997) - Utterly insane, but I still love it as a Warhammer 40K origin movie, because it fits so dang well in that universe. 
28 Days Later (2002) - A great watch that started the zombie revival of the 2000's and holds up really well, unlike the sequel.
The Others (2001) - Even though it relies on a twist at the end, after repeated viewings, I still find it a fun watch.
The Mist (2007) - One of those movies with characters you love to hate, but has a wonderfully creepy vibe.
Alien (1979) - It's a classic that's hard to top, and none of the sequels provide the same atmosphere. Unless you count Alien: Isolation.
Carrie (1976) - A bit slow paced and intentionally awkward, but builds up to that great ending.
Invasion of the Body Snatchers (1978) - Spock investigating alien possessions? Sign me up!
Cronos (1993) - Vampires and Ron Pearlman = guaranteed winner. Go check it out.
Misery (1990) - Also never gets old after repeated viewings and is a must watch.
Christine (1983) - One of the few movies to both fascinate and terrify me as a kid and I still like it.
The Crazies (1973) - Hokey and cheesy by today's standard, but still has some mind bending and unsettling scenes/imagery. Don't bother with the remake. 
Pet Sematary (1989) - Another one of the all time greats and also has it's own Star Trek Alumni. 

Virus (1999) - Totally a guilty pleasure, some say it's pure garbage, but I like it anyways.

Silent Hill (2006) - Yes, the one based on a video game. It's got a disappointing climax, but still a great movie otherwise. 

The Changeling (1980) - George C. Scott in a ghost story not associated with Christmas. It's good.

Now at the same time, there are plenty of movies that tend to mix genres, like action-horror and comedy-horror, but I wanted to leave as much of those out that I could and focus on movies whose primary goal is to just be a scary movie.
