I watched this OVA for the first time when I was around 10 and I found it hilarious. It kept on my mind ever since and I was able to watch it again now that I'm 27 and have a big "anime maturity". So what do I have to say about this? It's still hilarious, although I can add some more things like "insanely hilarious". Nevertheless, don't expect top of the notch story here, this is something more of a scene by scene with not much content behind it stuff. Anyhow, it has some great animation and graphic quality -keeping in mind is anime from the 80's- So, if you're looking for a great lough, simple-plot (and sometimes even a litte disconnected story-line), neat animation with great graphics, sci-fi anime with cool actions scenes, here's your answer.
Oh, great character design as well
