Now that it's fully out (last episode), I'm recommending this show.
It's dubbed in 11 languages and you can watch for free on YouTube.
The characters and dialogue are great, not just by indie standards (each episode is ~3-5 minutes) but by general anime standards.
Super human Chiharu and cyborg Makina got arrested for breaking space traffic laws.
They're stuck with a crew of misfits who got caught around the same time: Akane and Kanata, the super human pair; and Kurt and Max, the cyborg pals. Ryoko, the police officer, sentenced them to clean up the interplanetary train – the so-called "Milky☆Subway," as their community service.It should've been a simple job – until the train suddenly takes off into deep space! The crew scrambles in confusion as chaos unfolds onboard!
No purpose! No principle! No point!
A never-before-seen space-train spectacle, powered by nothing but pure momentum!
Did it get better? I loved the music video from a while back. However, I watched ep 1 of the series and it was underwhelming, so I dropped it.
The rest of the series has roughly the same tone and quality of writing, although I particularly liked the writing in episode 6.
If you bounced off episode 1, it might not be your cuppa, but the whole series (YouTube playlist) is less than 45 minutes long if you want to see for yourself.
I had the same feelings about the prequel (Milky Highway) but enjoyed this (especially the story, even though it is not mind-blowing it is a nice arc) a lot more in the series.
