Not bad, but not good, either.
The animation was a bit on the flat and uninteresting side. The art itself was great, but since you didn't open anything up to multiple shots, or animate things in full 3D, much of it seemed a bit rigid.
The story was a bit cliche, and I think way too simplified (and the narrative was rushed) to really have the effect you wanted. The end shot with Earth in the sky was very cool, and a great note to end on. But the rest of the piece seemed to be an excuse to get the audience to that moment.
Some of it didn't seem to make sense. I know everything is supposed to be odd and confusing, and there is supposed to be a level of mystery behind everything, but, really... some of it was a bit silly. You may imbed an excuse (or "explianation") for this later, but it really seems silly for aliens to abduct someone and then not only give them weaponry that could kill them, but not supply the proper security to prevent that from happening.
I do like the idea of throwing the everywoman into an odd scenario, but it did seem rushed. I'd have liked to get to know the character a bit more, and I think there should have been a little more tension leading up to the abduction, or atleast a better abduction scene than the age old radio fritz cliche.
The shaky camerawork added alot to the piece, especially early on in the car. I think later the shaky camera thing became a little overused and annoying, but if you fleshed a scene out to have more than one angled shot it could have worked much better.
The voice acting seemed a bit staged and lackluster, for both the main character and who we're lead to believe is her boyfriend (or x-boyfriend now, I suppose). I think you needed better voice acting in situations like these, because they're very intimate and rely on subtleties.
Overall the piece was barely below good. I want to give you more credit, because the art is nice and I like where you want to go with the story, but I don't think any of the elements in the film get you there. Great moment to leave us with at the end there with the Earth in the sky, but other than that this piece is a bit underdeveloped.
Good luck on the next one.
