Timeless

Most of this episode is fine. It has a fascinating premise and it is nicely put together. There are some "buts" however. The business of changing time is still out there in the realm of impossibility. How humans can change it, is also beyond me. But, we need it for science fiction, so let's give it a pass. The one issue that bothered me here is that the cause of all the problems is a blind trust in Harry Kim, knucklehead at large. They had run 20 simulations and each had ended in problems. Enter the impatient Kim, and a little speech allows him and his friend Tom to go off into the ethos with no regard for testing. Anyway, the dark future is interesting and the effort to correct a fatal mistake are fun. One last thing. Don't give Harry any responsibility that affects the lives of the crew.
