When I first saw “Hot Fuzz” (2007) on DVD, it was around the same time the unwanted “Vacation” reboot was in theaters (and incessantly subjecting me to an unfunny commercial where the family is swimming in poop). What a difference. Comedy is not dead. “Hot Fuzz” is cleverly funny and has a plot. It has peepee jokes and has a plot. It has cartoon violence and has a plot. It name checks other movies and has a plot. The plot? It’s a simple cross between a buddy cop movie and an episode of “Scooby Doo.” But. It. Has. A. Plot.
