Honey I Shrunk The Kids (1989)

Inconsequential piece of silliness that inexplicably spawned two sequels. A hapless inventor (Rick Moranis) has created a device capable of shrinking objects to minuscule size, which only works in accidentally shrinking both his and the neighbors' kids. There's much promise in the premise, but it lacks energy and grows tired quickly, and aside from Moranis, most of the performances are decidedly forgettable (even "Max Headroom" himself, Matt Frewer, as Moranis' long-suffering neighbor). The special effects are all top-notch, however, and are expertly employed in the service of a couple of good set-pieces -- including a battle between an ant and a scorpion and a flight on a bumblebee -- that make up the film's most memorable moments.
