5/5 Greatest season of sealab!

This sealab season comes with the series' greatest episodes. The other seasons are funny, too, but I like this one the most.

2/5 Funny, but ultimately Empty and Soulless.

Let it never be said that Sealab 2021 was not funny.

It is very funny, and like Space Ghost Coast to Coast and other similar "Adult Swim" shows, it has perfected the art of using crude sarcastic randomness overlaid upon earnest-looking 70s art to make you laugh. (I have come to think this is kind of a cheap trick.)

But that's pretty much all it does. There's no interesting story, just the most bizarre sequence of unrelated events you can imagine. The jokes are not particularly smart, they just consistently hit that sweet-spot of randomness. The characters usually all die in every episode, preventing any plot progression or consistency. There's no original music to speak of save the catchy theme song. The animation reflects a clear minimum of effort.

In conclusion "Sealab" is funny, but it is devoid of other entertainment-value content. So in my personal view it is 2 stars, it's entertaining, but not really worth watching.

5/5 It's great

Sealab 2021 is one of the funniest cartoons I've ever watched. Narrowly edged out by Earthworm Jim. This DVD has some great episodes - Lost in Time stands out as the most side-splittingly hilarious. Definitely worth the money.

1/5 Sealab 2021

I was very disapointed with the movie. But the product was in good shape

5/5 Another great Adult Swim show
  by Steve (Kenosha, WI)
Sealab 2021, a show making fun of a short lived show back in the 70s, is like Cartoon Planet but with Sealab. A show that lasted for 4 years and passing the number of episodes of the original show. This and the second season were the best (and I never saw any episodes in the 3rd, 4th or 5th seasons) ones. Who couldn't forget the great, psychotic and racist Captain Murphy? or the innocent Dr. Quinn? or the idiot known as Stormy Waters? This had great episodes like Happy Cake Oven or When Captain Murphy was crushed and trapped under a soda machine and having a scorpion as a pet and giving him venom to live. also includes I, Robot, the episode where everybody except Dr. Quinn talk about being a robot, and Stimutacs. Recommended for Adult Swim fans and anybody else.
