The AV Club’s Noël Murray:

[T]here’s a lot of ​“best” to M*A*S*H, such that the 10 episodes highlighted below (and the 10 listed below that) barely scratch the surface of what the show has to offer. A bad M*A*S*H – and there are plenty of those, too — can be insufferable. A good M*A*S*H is sublime in a way that few sitcoms have even tried to be, before or since.

I’m not entirely sure that there is a bad M*A*S*H episode.
