Finally got around to watching the first season. The ending was kind of disappointing tbh, lol. I watched the majority of it on one sitting so it's a bit of a blur of what happened episode to episode, but my over all felling was that it was okay. A lot of basic information was skimmed over and it definitely felt like an adaptation if you know what I mean. It just feels like there should be more information regarding how Ghouls function, their society, politics involving them, their relation to humans, etc. that should have been that should have been presented already but wasn't.
e.g., The Kagune and Rc Types were never really explained. These are things I briefly looked up at the Wiki to understand. I didn't even know the Kagune was an "organ", I assumed it was some sort of spirit...manifestation...thing.
I haven't gotten to the manga yet, but I'm planning the check it out after I catch up with season two.
