I think it's a better idea to necro bump this rather than make something new...
I wrote a review for Blue Friend/Blue Friend 2nd Season, since 2nd Season is one of my favorite mangos. As you can see in this topic, Blue Friend is not actually hosted here due to the wishes of the scanlator, but mercifully you can still fairly easily find the entire thing in English.
It is my opinion that the 2nd Season (volume 3) of this manga is quite a lot better than the first (volumes 1 and 2). They're completely different stories, and the 2nd Season story is pretty lighthearted and nice while also examining some interesting culture things. The first story is quite dark, however, and fairly depressing, but it's admirable how bold it is.
I go over this more in the review I wrote, which I'll post now:

I figured making a thread that started with a review of mine would be in poor taste. Poorer taste than bumping a three year old thread.
