The plot really dives down an interesting path that really fills in blanks that I don't see many animes do really. It's a first for me, or least one I haven't seen far to often. So you will be quite pleased by how this anime plays out. It really sets up the story for later on.
I felt I was on the edge of my seat at times also. Even shed a tear or two. If you're really into this, then I think you'll enjoy it. If you're still questioning to watch this, or the anime in general and are just looking through reviews, then I say give it a shot! You'll enjoy it!
