It’s a seinen. If you’re more into shonen, then it’s not going to be as action-packed as you might be used to.

I don’t normally watch the same thing more than once, but I’ve seen this one three times (first time in college; then some years later I wasn’t sure I finished it the first time, so I rewatched the whole thing again; then more years later I watched with friends from work on our weekly anime night)
