Really pretty darn good.  It was real nice to look at.  I’m not sure the ending was the best though.  But maybe it was.  I don’t know.  I thought the premise was interesting.  I liked how they incorporated some cool sci fi concepts.  But I thought that all seemed a bit jumbled.  They had a neat central idea, but I don’t think they applied it consistently, nor did they fully explore the concept.  But that’s nit picky.  It’s a very engaging sci fi, with many nods to your favorites of the genre.  I thought there were some very subtle details that they conveyed pretty well, but there were some larger and deeper themes that they touched on too lightly to flesh out.  All in all a pretty great flick.
