first episode was pretty interesting. Getting a little tired of seeing super moe cute girls placed in the role of heartless killing machines though... The investigator and the policewoman seem to be tolerable characters, although I'm more interested in the criminals.
I still need to watch the second episode but I really don't know what people are comparing this show to Bebop for. No bounty hunters, main character is a friggin federal agent and I've yet to see anything involving martial arts or dog-fight space combat yet. Not to mention the difference in the sound track.
Again though, judging all this from the first episode is a little much. I like the "space outlaw" genres quite a bit though, and will casually pick this show up.
