Like most girls horror authors, Watari tends to the "creepy" rather than the gory. Her works are aimed at a primarily teenage audience, but contain little graphic material. This, along with the fact that any one of her volumes can be read independantly, makes her a good choice for readers new to girls horror.
NB: For some reason, the "e" in "Chie" often appears in lists written with different characters (江, 絵). Ive seen no actual evidence that her name was ever written differently, but if anyone has any information about it, please let me know.
