After the success of Jurassic Park in 1993, the floodgates opened for digital special effects, and Jumanji is nothing if not a showcase for computer-generated creepiness guaranteed to give young children a nightmare or two. Whether that was the filmmakers' intention is up for debate, since this is a PG-rated adventure revolving around a mysterious board game that unleashes a terrifying jungle world upon its players, including gigantic spiders, huge mosquitoes, a stampede of rhinos, elephants, and every other jungle beast you can imagine. Robin Williams plays a man-child who's been trapped in the world of "Jumanji" for 26 years until he's freed by two kids who've discovered the game and released its parade of dangerous horrors. A chaotic and misguided attempt at family entertainment, the movie does offer a few good laughs, and the effects are frequently impressive, if not entirely convincing to the eye. --Jeff Shannon
