Sorry, folks, but I watch TV to be entertained. Particularly when I am viewing Sci-Fi shows, I suspend reality and accept certain premises that may be technically flawed. By doing so, I'm not over-analyzing every nuance trying to figure out if it's consistent with current scientific knowledge.
With that said, I am apparently one of the few (along with my husband) who truly likes Timeless. Each week I look forward to the historical period in history where the characters will go. Besides that, there is the underlying story of Flynn-- who he is, why he's so protective of Abigail Spencer, what his true motives are (good? evil?) as well as who or what Rittenhouse is and why it wants to change the course of history.
I genuinely hope NBC gives this show a chance. There hasn't been a good time travel show for a while (I remember watching Time Tunnel as a kid!) Perhaps there's room to improve Timeless, and I think a lot of successful shows start out somewhat shaky, but I'm already a fan.
