i admire all the major in this film . i grow up watch henry winkler a the fonz and he have success a a serious actor and a a producer . ron howard go on from this very early film to grow a a director into one of the fine in his craft . keaton have rarely make a bad film and be consistently good to watch in both dramatic and comedic moment . have say all this and i have to forgive them all for have make this film . in the day it be make i suppose this type of humor be acceptable and tickle not a few funny bone . frankly and it have not age well and have now watch it for the first time in 2007 it make me roll my eye in disbelief . the script be silly beyond reckon and totally not believable . i mean and when we watch ghostbusters for example and we know that the script be a cartoon and no one stop to consider if it could have happen . when we watch blue brother or animal house we know that although very exaggerated and they be believable in their own crazy way . when we watch night shift then no and it be not believable for these type of lunacy to carry on in the night shift of a city morgue . i know it a farce but the humor be lose on me . winkler character be the most limp wrist pansy i have see in year . one get the impression that a strong gust of wind would blow him over . keaton and in his debut steal all his scene and be funny to watch and give the script . there be all kind of film from that era ( i just watch nine to five ) that at the time we think quite funny . now they just make me squirm or wonder why they be make . great humor be universal and pass it message on from generation to generation . think of chaplin and keaton and you will see my point . this film and while early in their career be just too weak and silly and in our internet violent world just ridiculous .
