It's a tough show to review because each episode is a stand alone movie. Some of these 'movies' have been some of the best tv I have seen. Some are just mediocre and increasingly more often in Season 5 & 6 where majority of episodes are mediocre and no stand out. I'm giving this a 9 out 10 just by looking at season 1-4.

One reason I love the show is because it's a unique program often full of dark futuristic stories that really make you think about technology now and the future but also about broader human nature in stories unrelated to tech or the future. Taking chances like this will of course produce some misses but the mystery is what the story will be be about is addicting. In S1-4 it was often difficult to know where the story going -- often surprising you a few times while keeping you in suspense. S5 & S6 are less surprising and less important topics or just a bit too out there. I give S5 & S6 a 6.5/10. Worth a watch but not thrilling like first 4 seasons where I was hooked on the show.
