Took a week but NieA 7 is ready to go.

This slice of life comedy/drama revolves around the lives of cram student Mayuko, freeloader alien NieA and the residents of Enohana.
Mayuko is a poor student who can barely afford a decent meal who lives in the upstairs of an old bathhouse, along with NieA a freeloader alien obsessed with food and building UFOs from junk.
In this world, aliens have made contact and are already living among humans with some aliens becoming living stereotypes of certain cultures in order to better understand human culture, notably the crazy Indian shopkeeper; aliens in this world are identified by their antennae, the better quality antennae the higher on the hierarchy you are, however NieA lacks an antennae making her an under 7, a term used to describe low class aliens.
A typical day in Enohana is Mayuko dealing with the daily shenanigans of the locals along with NieA, then after episode 6 we deal with six episodes of depression as we witness a full cycle of Mayuko's social anxiety before normal service resumes on the last episode, nothing is resolved, no questions are answered and you'll be asking for alot of time back.
Not to say it's bad, you do learn alot about mental illness and how narrow minded society can be in dealing with these problems, but the first half made this out to be a gag comedy and to sit through the second half was like reading a newspaper after watching Looney Tunes. You forget why you laughed and are suddenly feeling depressed over whoever died that day or whatever crappy thing the government does next. It's not so much a mood whiplash rather a mood kick to the balls.
Saw the sub and heard NieA's voice and was glad not to have seen the dub.
Final Verdict: Being honest you wouldn't lose anything by stopping after six episodes of the anime, unless you're into social commentary on anxiety, discrimination and stereotyping you're better off skipping the second half of the series.
