Totally understand. But let me tell you that the manga is QUITE different in the second half.
Kaneki doesn't join Aogiri. He does leave Anteiku but you will understand his motives a lot more.
Also, there aren't as many plot holes in the manga. It explains so many things that just happen in the second season .... where a lot of things happened so quickly and didn't make sense, right? ^^
I recommend to read the manga!!!! :D

Glad to hear you loved season 1. ^____^
