Though Adventures in Dinosaur City predates We're Back, the two films make good companion pieces. The "live action" characters-a bunch of precocious pre-teens-are zapped back to prehistoric times. We've established that the kids idolize a group of animated TV-series dinosaurs, so guess who they meet in the flesh (so to speak)? In the manner of the "Pebbles and Bamm-Bamm" segments of the various 1980s Flintstones revivals, the kids help the dinosaurs solve Jurassic-era crimes. It's all a great deal of fun, but at 88 minutes it may be a bit too wearing for very small children.
