I gave up on Helix, I don't know why, just got tired of it. Same for Arrow and Flash. All three are "good" but I found myself in no hurry to watch them so I stopped wasting my time on them. I would rather look for an interesting anime I haven't seen, lol. Attack on Titan was excellent too, especially the first few episodes. If only American TV could write as good as some of the Japanese animes. When I was younger mini-series went through a phase in american tv, some of them were epic (Rich Man, Poor Man). They should try that again but instead we are stuck with cheap reality shows and a greedy actors guild that forbids making affordable quality tv. I mean I just adored Breaking Bad but it cost around 3 million dollars per episode to make.....an unbelievable fact but true nonetheless.
Hehe just did the same with Helix first season was great but 2nd one has lost its way, So now i am watching knights of sidonia, so far its a good show its a bit slow up until episode 3 or 4 but now it is very good, As for TV i gave up on it about 7 years ago i would rather stream my shows than watch TV just to much crap on these days, used to be good but British TV has took all the great ideas from the past and recycled them into so called new shows.
