I have a massive emotional attachment to the original Vacation films. Basically, my dad is Clark Griswold. Those movies are considered classics in my family and are quoted on a regular basis. When I heard that they were passing the torch to son Rusty Griswold, I was nervous about it just being a lame and half assed attempt to reboot. Happily, I was wrong. This movie was pretty damn funny and had great family messages through all the gross visuals and some pretty crude dialogue.
I would definitely recommend people checking this out. It's a bit raunchy at times but pretty funny and a worthy entry in the Vacation series.
