Pros:
`More attention to inking and toning. Creating more delicate look.
`character relationships are more connected.
`there's more logical reality (aside from ‘fantasy’ elements)
`It's long enough that one can get very attached to the characters
`much of the story progresses the plot
`I believe it's fairly good at plucking at your heart strings (if you like that kind of thing)

Cons:
`It does include a cast of angels and demons, which many might consider unoriginal
`It is greatly character driven so there is more dialog than action
`There are a lot of themes and situations that might make people uncomfortable.
`It has a slow start before all the story and drama really get going.
