Okay first let me say don't read this if you haven't finished the series there will be ***spoilers***
I just finished the series and I loved it! All of the reviews I read gave this show a bad rating because they said it was a bad ending and or Alan should have found a way to get free / Sam should have come to his senses and decided not to kill him thus leading to a season 2. This is why I liked it! This day in age T.V. shows and movies are so predictable! There's always a happy ending. It gets so old, repetitive, and boring. This was much more realistic and the bad guys win! Could the ending be a little bit better like say Alan puts up a good struggle? Yes, but I'm glad to finally watch something that doesn't have a happy ending, and doesn't fit the rubric every show and movie has these days. A+ for being realistic, not everything in life has a happy ending, especially when we're dealing with something like psychotic serial killers
