Designated Survivor is brilliant - cant wait to see the second season
I have been enjoying Chernobyl as well
Line of Duty is a must watch
Harrow is turning into a good series so far
Looming Tower is also very good and from the research Ive done, quite accurate in its portrayal.
I had been enjoying Lucifer but the 3rd season let it down badly and I cant seem to pick it back up again.
Elementary is one of the best series Ive seen in a long time and I would recommend that to anyone.
I've effectively answered this on the other thread but here goes anyway. The only programmes I consider 'unmissable' throughout an entire year's TV are:
1. Jool's Holland's New Year's Eve Hootenanny, to get the year off to a good start ;
2. The Eurovision Song Contest (which I forgot to mention on the other thread), including the semi-finals ; and
3. The Voice Kids.
