Another Remake, Reboot, and Retake on a tired franchise. Vacation tries to poke fun at itself like 21 jump street but still tries to hold its composure. The good thing is it's in a format of skits once they hit the road. If you don't like what you are watching, give it 2 mins til the next pit stop/skit. It has it moments and then it doesn't.
Go ahead and take a piss... U won't miss any knee slapping or gross out bits.
