A single mom accidentally reads a scary book to her mentally-disturbed kid, thus summoning the title horror. The book (especially its illustrations) actually is kinda spooky, which of course raises great wonderment about why a parent would read such a thing to her already nervous son. Likewise the monster itself turns in a few frightening appearances. The shocks are more or less enough to offset the annoying characters and relative plotlessness. Verdict: mildly amusing.
