Elliptical Orbit:
Fifteen years after its last contact with our world, a space freighter known as the Flying Dutchman requests permission to dock at a remote moon base. This mysterious ship carries liquid protons: a power source essential to the survival of Earth’s population. But before the precious cargo can be delivered, the base is ambushed by galactic terrorists who seek to destroy the new form of energy and issue a death sentence to all of humanity.

Symbiotic Planet:
Against a backdrop of intergalactic colonization and bizarre alien life forms, Aon and Elena – star-crossed lovers from rival countries competing for valuable natural resources – struggle to build a life together despite the objections of their superiors. Their budding romance is thwarted by an outbreak of alien fungus and the interference of a cutthroat militaristic madman. To survive, the young couple must maintain their faith in each other and learn to trust the unique creatures which inhabit this strange and wondrous new world.

Science fiction is arguably one of the most diverse genres in visual media, with series like Stargate, Farscape, and Babylon 5 enjoying a fair amount of commercial success. Even more than this, both the Star Wars and Star Trek franchises have become household names, and the impact of these two franchises dwarfs that of more recent shows.

However, while television has enjoyed several successful science fiction franchises, it is anime that has produced more sci fi tales than almost any other medium. From space opera to cyberpunk, from utopian dream to dystopian future, from aliens to mecha, anime has, throughout its history, produced some of read more

When I picked TO up, its MAL rating was at 6.75 (and is probably going to get even lower). Daunted by this low score, I didn't know whether to watch it or not.

Thank God I did.


- Art/Animation. Though this show may be 100% CG, it's 100% good CG. The second episode proves that. Save the characters, everything is so beautiful. There's no glitches and mishaps you might see with hand-drawn works.

- Soundtrack. A lot of the time, the show simply pans out to let you soak in the art. And it plays some great background music at the read more

This show felt incredibly awkward. The dialog, the art, and the relationships between the characters.

The first and second episodes share nothing in terms of story. The first episode is about human relationships in space when people age differently. It's been done before(and better) but an interesting idea none-the-less. Instead of pursuing that idea to it's fullest they decide to just throw in one of the lamest generic bad guys I've ever seen. It does have an interesting twist, but it doesn't really justify watching the whole thing.

The second episode is about 2 lovers on an another planet that just happen to belong to read more

[b]TO[/b] is really two beautifully illustrated science fiction short stories presented in classic anthology style. Generally speaking, I am a "CGI hater" but [b]TO[/b] is a glimpse of what we can look forward to as the art evolves. It is high budget CGI at its best featuring stunning spacescapes, ships, equipment, and interiors, but as usual, human movement , facial expression, and lip flap leaves a lot to be desired. Human movement does seem a bit more fluid in the [i]Symbiotic Planet[/i] than it does in [i]Elliptical Orbit. [/i]Thankfully the voice acting, even in the English dub, helps make up read more
