Comedy sequel where the 'weird' world of adults is seen through the eyes of a child narrated/voiced by Bruce Willis.
James The Cab Driver (Travolta), Molly The Accountant (Alley) and Mikey The Baby return with one new addition, Mikey's little sister Julie. Again, the comedy mainly hinges on the gimmick that Mikey's thoughts are given a voice by wisecracking Bruce Willis, and now little Julie has her own voice courtesy of comedienne Roseanne Barr.
The idea isn't as effective second-time around, as Willis' voice often fails to correspond to the older Mikey's mouth movements. The story (what there is of it) centres around Mikey's acceptance of his little sister, and James and Molly's explosive marriage, which is not helped by the arrival of Molly's brother Stuart (Koteas), an unemployed accountant with a penchant for pulling a gun on James, thinking he's a burglar.
There are some nice comic sketches worth looking out for, like Mikey's terror of Mr Toilet Man (voice supplied by Mel Brooks), and John Travolta's mad dance at Mikey's playgroup over some kiddies' gym equipment, that bears a striking resemblance to his routine at the end of Grease.
But a few amusing sketches do not a comedy make, and although both Travolta and Alley reprise their roles with ease, they can't make up for the weak plot which flags in the middle, so much so that the director treats us to a five-minute montage of Mikey's facial expressions and flashbacks as he thinks about how badly he has treated his kid sister, all to the tune of Jealous Guy.
