Set in modern times, vampires roam the earth and are humans mortal enemies. However, a substitute has been found for human blood, a substitute that vampires can consume with the same effect as human blood. This is True Blood. Now humans and vampires can coexist in harmony, and even form relationships. But there will always be rogue elements on both sides ready to exploit the uneasy truce.
Superb, for the first few seasons. Original, uncompromising and highly engaging. Great character depth, clever, intriguing plots, interesting relationships and good performances. For 5 seasons this was fantastic.
However, the producers didn't know when to quit. The writing was already starting to feel a bit jaded, with retreads of previous plots and characters and, especially, different life-forms being introduced just to give the illusion of originality. The final two seasons were mediocre, at best.
The final season, Season 7, was particularly bad. No originality and the writers and actors seemed to be just going through the motions. Watching became a chore, something I had to do so I could finish the series rather than watching because I enjoyed it. Season 7 may well be the worst final season in the history of TV, especially when compared with what came before.
