If it came to a push between vol 2 and vol 3 I wwould be in a bit of a quansrary, cos I dislike them both equally. No characterisation apart from the newbies, kinda like the writers didn't really want to explore the originals who had made Alpha so good in the first place. Volume 2 did get a little better towards the end while three was only barely interesting for the last arc, so on that alone I would have to give it to volume 2. Although it does pain me having to put volume 2 above anything
