This modern take on 50's Sci-Fi films is indeed gross, and definitely scary, but compared to other modern day Horror films this is not to bad. The only real blood you see is green spider blood, which you have probably seen in "Gremlins" (the gremlins had green blood), and when people are attacked you can really only see the spider on top of them wiggling around. The violence and special effects can be scary and really creepy, but that's usually how it works with over size bug (or should I say arachnid) movies. There is sexual references, and two people briefly make out in a car. Finally, some of the language is ruff, and maybe sometimes unnecessary. So after all I've said parents you should keep children away from this film. But other than that this spider movie is a good choice for a monster movie marathon, and though Common Sense denies it, it has a few little comedic moments that will make you laugh.
