Nothing wrong with reading for escapism, though I would not say that it was good for you except for relaxation.
But reading the same type of thing over and over and not exposing yourself to new ideas and ways of thinking is no better for you than watching "Big Brother" on TV.
On the other hand, much of the sci-fi that I read for entertainment as a teenager exposed me to some concepts new to someone growing up in the rural South. Especially the better writers like Heinlein, Delany, Leiber, Ellison, Clarke, et al.
Still, I know educators and librarians are all for any method to get kids to read, but Stephanie Meyers is more likely to lead to Barbara Cartland rather than James Baldwin.
