I watched Under the Dome, it was very confusing, but I stuck it out to the end of the episode. I will give it a few episodes to see, but I wasn't impressed w/ season 2 so far.
I watched the new episode of Extant, that looks very promising.
Also The Zoo had a good start.
I don't know about Lost Ship, but have been watching The last Ship (or something like that) and it has been pretty good, but very violent.
