Not very scary movies

Well it's a question of personal tastes. What one mind find terrifying another might not be scared of at all. If you're not a hardened horror fan like some of us here you'll probably find yourself more comfortable in the realms of Slashers or milder splatter movies. Giallos are a great introduction to horror in a mild form. I highly reccomend trying out Argento's movies and slowly ease yourself into the more horrific movies. Avoid movies with disturbing subject matters at first. There's plenty of time for those as you become more acustomed to the more extreme. But some people will happily stay in the comfort zone of slashers. Zombie movies seem to be a favourite of none horror fans I find or post apocalyptic movies.

I find a lot of ghost storys pretty scary but I like the feeling of being scared I really don't like the PA series but I find it too difficult to believe any of it. Give some of the slasher series a go, Scream, halloween (originals, newer ones are a bit more out there for the extreme), Friday 13th if you haven't already. George A Romeros living dead series and it's remakes. Most you may have seen but if not, they are a good start.

You might like The Stand (1994). In Christine (1983) director John Carpenter proves that a car can be scary too, but it's not too scary so you may watch that along with The Car (1977).

Try out Evil Dead 2- it has some scary but is also rather humorous.
Army of Darkness, also.
You could try the old Universal horror films, ala Dracula, Wolfman, the Mummy. Also the Hammer films from the 60's and 70's.  DirtyGirl can fill you in non the Hammer films.

Also comedy horror, like Shaun of The Dead is a bit scary but the comedy tones it down a lot. I find sci-fi/horror to be some of the least scary films I've watched. Ultra has given good advice, watch the classics and especially slashers; they are fun and light on real scares

if you like zombie movies but not too scary "Fido" should be ideal.

Try something like Joy Ride,Riding the Bullet,Let the Right One In and then with some classic slashers...

I got the perfect movie - A Serbian Film!

That film and it's remake were so disturbing so I... turn them off before I finished. Gotta finifsh them.
