[spoliers] Unusual and somewhat interesting
Its abstract visuals are a treat, if you're a big fan of "visualizers" in music players (WinAmp anyone?).
They actually don't just visualize the sound we hear from the dialog and some sound effects. They do in some cases also serve some visual cues.
The episodes seem kind of disconnected at first, but gradually the theme of time becomes apparent. Then, maybe for the last 3-4 episodes, it's obvious: they're all part of a more intricate whole.
The story is a bit reminiscent of some Twilight Zone stories where conversations are happening forwards or backwards in time. Actually not sure if there are any such TZ episodes, but I guess you know what I mean.
There's not any twists, really: the enjoyment comes mostly from the unfolding story, where more and more details are revealed allowing the viewer/listener to puzzle the bigger picture together. And maybe also the scientific stuff of quantum multi-verse and whatnot, for the people so inclined (me included).
Sure, I enjoyed it. Would I want more stuff like this? Not really.
