Common Sense Note
Parents need to know that, while teens are definitely going to want to watch this comic book-like fantasy drama, it's at the far end of iffy due to its significant graphic violence. A central character who's incapable of getting injured frequently suffers debilitating injuries (burning, falls, mutilation), only to walk away unscathed; there are some disturbingly gory murders (heads cut open, bodies impaled by knives and other sharp objects); and explosive images of potential Armageddon are frequent. The show also has some relatively mild sexual content and language to watch out for, but the violence is the big issue here.
One of the original "heroes" is a Las Vegas stripper who runs a Web pornography business out of her home and is shown stripping for a webcam (no real nudity) and seducing another character in her underwear. Other characters are shown in bed together (no sex on screen), with implied nudity. In at least one episode, two young women share a kiss.
Significant amounts of blood and guts, and several graphic murder scenes. Some of the visuals are shockingly gory and may turn even the strongest of stomachs. Characters are constantly in peril and/or risking themselves to help others. Frequent images of potential Armageddon -- explosions, destruction, etc. The characters' goal is to prevent that from happening, but the images are frequent and scary.
Occasional use of words/terms like "crack whore," "bitch," "hell," "hump," and "screw."
Overall the show's messages are similar to those of most superhero stories -- it's right for good to triumph over evil, characters who see the light deserve a second chance, etc. But plotlines can get very convoluted, with characters changing sides/alliances frequently, and it's sometimes hard to keep that in mind.
Some product placement (cars, etc.)
Drugs / Tobacco /
One hero has a heroin addiction; other characters (including some underage) are shown drinking socially on occasion.
