It`s best not to take advice from huge fans - they have a tendency to get tunnel vision about their favorite shows.

I am going to second the recommendation for 蟲師 (But be sure to ignore the live action movie adaptation like it is the plague...) 図書館戦争 is also one of my personal favorites (although the novels are better - they cut the last book altogether and replaced it with something entirely different to end the series early.)

I would avoid most of the longer series, as most of the time they string them out to the point that it`s just anime for the sake of anime.

Anime based on 小野不由美`s novels are also good - 十二国記 and 屍鬼 for example.

My husband praises 放浪息子 to no end (I haven`t had the time or courage to watch it), but that may be because we`re concerned with something similar happening with our son.
