Not true at all, I've seen some pretty soft hearted girls get addicted to Dexter, the blood doesn't bother them at all for reasons unknown. I read a psychology article behind it, check it out.sandy453 said:Here is the season 1 trailer you can show her
YouTube - ‪Dexter Season 1 Trailer‬‏
If your wife doesn't like seeing blood on the screen(lots of it as well as dismembered body parts) ,then this serial is not meant for her . And, also there is some nudity involved.
