[SPOILERS S3] I watched the entire series and I think they ruined it.
When I was watching season 1 I loved it, the plot, the excitement, Cinematic view, it was all fresh to me. Even tho I didn't like season 2 as season 1 I still enjoyed it. But I noticed that they couldn't keep up the thing that they had in s1 and it was slowly getting away. By the time I was watching season 3 aw god I hated it, I completely loosed the interest of the series. I was watching almost the same thing I watched in s1 for 5-6 episodes, it felt like I was watching 6 hours of fillers. also I felt like the series also got so much sci-fi, more than it should. I think it's overrated.
Anyway I finished the series and this is just my opinion. I respect others. Just wanted to share it with you guys.
