The amount of fanservice can be pretty funny, as nearly every female character walks around with very little clothing on and most of the men are shirtless or with well-toned muscles.
The CGI special effects, while good for 90s television standards, look pretty hokey today.
The final episode has a funny moment when Raiden tries to zap Shao Kahn, only for his powers to fizzle out. He grunts and points at him and there's no lightning. So he tries it again, to the same effect. Even Shao Kahn laughs at him.
