To find out how entertaining M*A*S*H is you just need to watch two or three episodes. To find out how emotional it is, you have to watch "Abyssina Henry". But one hint: Watch the previous episodes first. The effect you'll gain will be much more satisfying then. After three seasons you have to like Henry Blake. His friends (Hawkeye, Trapper, Radar) prepare a wonderful good bye party. They drink quite a lot and it's very funny. The emotions for Henry are nicely played then and even better next morning when he leaves. The plot at the end of this episode is so surprisingly that you wouldn't expect. One of the greatest episodes all over the millions of TV-series there are.
