In order to catch the malicious time-shifting aliens, Picard and some crew-members use their knowledge of their time-travel technique to follow Data and the still unexperienced Guinan on Earth in the 19th century, where author Dr. Samuel Clemens' persistent inquisitive suspicion is on to them. When the aliens' time-shift back is tested, Samuel Clemens is transported back aboard with the crew and starts pondering the advances made in five centuries of human and intergalactic progress, while Data is only retrieved after decapitation. In the past, the aliens try to put up a defense... Written by KGF Vissers

I kind of liked part one better.
26 November 2014 | by (Bradenton, Florida) – See all my reviews

In part one, Data was beamed back to San Francisco in 1893 and he cannot get back to the Enterprise. But the crew are able to come up with some confusing way to join Data and they learn about the weird creatures that have come to Earth's past to kill people and harvest the energy in the victims' brains and spinal columns. Naturally they have to stop this as well as all return to the present. There is a slight glitch, however, as Mark Twain (yes, THAT Mark Twain) learns about their plans and threatens the timeline because of this.

I enjoyed part one more than part two simply because I didn't love the Mark Twain angle and I also thought the character was a bit too hammy. He wasn't terrible--I just didn't like this in the story. Worth seeing, however.
