Very funny movie that started the Vacation series, which clearly peaked at Christmas Vacation.

The Griswalds are fully-developed characters from the off (well, Clark and Ellen anyway, the kids were always changing actors/ages), and it’s also fun to see Cousin Eddie also fully formed.

There are many laughs throughout, as mishap piles on mishap, and Chase starts acting crazy.

Great comedy writing from John Hughes, and great comedy direction from Harold Ramis.
