For family movie night this week we watched Honey, We Shrunk Ourselves (1997,PG) (ScreenIt! Review).  From ScreenIt!:

Two sets of parents are accidentally shrunk to miniature sizes and watch as their kids have a party.

This one, of course, doesn't take any unexpected turns...but it's enjoyable enough.  Lisa was shocked when I told her it was from 1997.  It seems like an earlier vintage.  Or maybe we're getting old.

I give it 3 out of 5.
