I actually really enjoyed season 1 of Invasion and then DNF'd season 2.
No more slow burn mystery, with lots of character-based world-building, and protagonists out of their depth putting things together from a limited perspective (with the audience usually one step - but only one - ahead of them). The second season is action heavy, with characters reduced to tropes who seem to have had a knowledge download and all become "special".
I've seldom been more disappointed in a continuation of something I loved.
