The Griswolds invite their extended family for Christmas, triggering an escalating comedy of errors. The best of the Vacation movies, this balances slapstick and subversion, with enough dark moments to give the movie substance.
The next generation of Griswolds go to Walley World. Sequel/reboot to the 80s Chevy Chase flicks; an okay episodic gross-out road movie of the old school. Inevitably hit-and-miss, but some genuinely funny moments.
