A chance encounter gets Wren (Victoria Justice) invited to the most popular boy in school’s Halloween party. She’s floating on air ... until her mom, Joy (Chelsea Handler), unexpectedly forces her to take her mischief-making little brother Albert (Jackson Nicoll) trick-or-treating instead. Albert promptly goes missing, which sets off a series of misadventures involving an abundance of kooky characters. Fun Size is a cute, if at times slightly annoying, little teen movie that adequately captures and celebrates the holiday. The movie has high energy and never stops moving, which makes its 90-minute run time fly by. The film is quite raunchy at times; it was definitely a shock to hear some of the cursing and sexually suggestive language a person might not expect from this type of movie, especially one made by Nickelodeon Films. It is definitely not for younger children, but if a parent were to take a little kid to see it, most of the adult humor would probably go right over the child’s head anyway.
