The naked gun never stops to be serious throughout the whole runing time. Usually that's a recipe for a unfunny mess of a film. In the case of this movie it is actually a recipe for success. The jokes in this movie are all halarious, and the slapstick is setup excellently. Also the characters are all stupid in kind of a smart way. Overall this movie is comedic genius and the best kind of slapstick. I recommend this movie very much, It's is a must watch.
