One of my greatest regrets regarding TV shows, is that I didn't watch 12 Monkeys sooner. It surpassed any expectation I could have about it, although the beginning of the first season didn't look that promising (maybe it had a slow pace, maybe too little things were explained), oh well, the sequels surely are totally worth watching. 12 Monkeys is so complex so well defined when you look at it as a whole, the plot, the ideas and themes expressed through brilliant acting... I know, it sounds too good, but it is really one of the most underestimated good sci-fi TV show, and it should receive all the appreciation for every amazing element it contains.
Also, it's extremely sad to see that it has such a low rating on IMDB just because of the ratings it has received in 2015, after only 1 or just 3 episodes appeared... when this TV show has a lot more to offer and it should've been "judged" at least after the entire 1st season. And it's not only that... I saw that many people complained how they liked the 1995 movie but the tv series disappointed them and I think that they simply can't be compared, it started with the same concept but there are lots of differences and the show really went with the story on its own way. I think they should've given it a chance and wait for more episodes before rating it with 1 or 2 stars...
