This reads like high quality fan fiction. The characters and dialogue are 90% spot on, the plot gets a little hand wavy, but that's mostly fine. 

The lower rating is mostly because of the accuracy of replicating and to some extent even expanding the content issues that bothered me about the original show. This was a fun experience overall, but not one I care to re-read. 

Be aware of general pervasive kidnapping and holding of prisoner content, sprinkled with torture and death, as well as some sexual content. One of the storylines follows a lesbian couple.
