I've seen all four DVDs for this anime and enjoyed every one of them. The begining lets you believe this is an other cookie cutter sci-fi/action anime but the ending has so many twist and turns that it makes it original. The characters develop nicely thoughout the series and some not untill the last DVD. The dub version is hilarious and the artwork is good enough. One of the best thing about this series(or worst depending on how you see it) is that it isn't vary long but it manages to fit in every necessary thing to make it intresting like plot and character development. The only objection I have is the ending, I wish there was more to it. Don't get me wrong its pretty final but I want to know what happened to the characters after the 'series' like what lives they lead.
