If you want your grade school child to be go through life exposed to minimal, paltry, vacuous, substandard educational material then this movie more than fills that role.
Plot: Grandfather takes screen viewing time devices away from grade school grandchildren (actually a good idea for lots of educational/psychological reasons) to instead read them a fantasy tale. Unfortunately movie quality does not match intent. Even the children, at one point, remarked, "predictable".
Grading:
Voicing choice for our "Guardians of the Galaxy" raccoon was unimaginatively bad (D-); raccoon & other fantasy creature animation quality - flat w/no detail (D); animation of electrical force fighting magical wands - cheap & overused; storyline of magical amulets & spells (witchcraft?) book w/usual latin incantations in a stereotypical evil vs. good battle for possession (an unimaginative ripoff, D); acting or lack of (D-).
Summary: Unfortunately cheapness makes money so they wrote in a sequel. Suggestion: Find fantasy that requires creative imagination w/thinking.
