Over recent weeks I've watched:
the first season of Taboo - One of the best new series in the last year - well worth a watch;
3rd season of Bosch - slow and boring - I only watch it because I read all the books and enjoyed them.
1st season of Cardinal - a decent Canadian detective series
1st season of Prime Suspect 1973 - possibly the most boring and slow series I watched to the end this year - shame after Prime suspect being such a good series;
1st season of Firefly - low budget sci-fi, a real easy and fun watch with some good humour.
4th season of Line of Duty - first 3 episodes and the last were great, the other 2 were stretching the believable.
3rd season of Broadchurch - same old boring stuff as the last 2 and very slow at times.
6th season of Homeland - other than the usual annoying lead character early in the season I found this season very good.
Presently watching
3rd season of Fargo - weird as always, I don't think it's up to the exceptional quality of the first 2 seasons but could yet be proven wrong.
2nd season Last Kingdom - I think I've given up watching it though.
3rd season Grantchester - it fills up a few empty minutes.
1st season of Outsiders - I think I've ditched it but maybe the wife will want to continue.
3rd season of Peaky Blinders - loved the first 2 only just started this one though.
