The terminator might be awesome for teens and older Tweens, this is a bit iffy for them for these reasons:
Violence: The violence level is at the PG-13 level, but still has blood in many scenes, though with no gore. However, there is a scene that's a bit gory with the terminator plucking his damaged eye out with the flesh attracting flys ( the reason he wears those sunglasses). Besides that, charactors are beat, stabbed, shot, and blown up repeatingly with many minor and even most of the secondary and main charactors getting constantly and instantly killed. A scary scene shows the terminator crawling towards the injured main charactor. Some dark post-apokoliptic imagery with skulls being crushed and cars & buildings being destroyed. There are many chase scenes on foot and in cars with charactors in constant peril.
Sex: One of the earliest scenes show the terminator naked, and though it is to dark and shadow filled to see his privates, his rear is shown. Sarah Connor and Kyle Reese are shown making love from the waist up, and her breasts are briefly shown. When charactors time travel, they must be naked.
Language: The languge is colorful, with words including sh*t, f*ck you, and asshole.
Drugs drinking and smoking: some drinking and smoking, but it is not a big focus.
My rating: R, for violence, sexual content, brief nudity and some language.
