This was a pretty good anime overall. The plot is interesting, and the story doesn't drag on like some other anime's. They could have made the plot a little bit more complex, but they didn't. The characters are alright, but they don't really go into detail on their lives, like some other series out there that only focus on characterization and no plot. But it is an "action" anime so that is understandable. There's a couple "extra" characters in it that are really useless but the series isn't long enough for them to get on your nerves. I personally liked the nurse and doctor themost out of this series. The rest were space fillers lol.
The animation is pretty good, since it's not such an old series. The opening and endings aren't all that bad if you don't mind jazz sounds.
