It depends your perspective reading. I personally like the story for character development and interactions. The plot was pretty basic and a bit predictable, as well as the ending but reading up until the later chapters around 50 the story becomes pretty dark and I get that the author wanted the characters together, but I would have preferred a sad ending. That's my opinion though. But you should for real give it a read if you haven't! :-)
I don’t think it was predictable because there were so many things that happened like you mentioned it turned Dark one point and it could’ve ended 3 different ways in my opinion and kept me on the edge of my seats waiting to know what happened next. In the Beginning of the Story i can see where you get basic but it developed pretty well. He could’ve stayed a actor, it could’ve been a sad ending or a happy ending or a happy ending but with out our top like this story was amazing.

...I could see what everyone else loves about this comic.
