The first season was an 8. Really enjoyed it. But the three following seasons ive gone down a point to 7. So it was still enjoyable. But still lacking compared to the first imo. So what happened? Well to me it just got bloated. There was to much of everything in the end. The first season hit the spot. The following crossed the line. To many characters. To many stories. It got hard to keep track of and lost its focus. I still enjoyed Durara to its end. Its a show i recommend. But it lost steam after season one and dragged on for abit.
