There's some intrigue in the opening of 'Time's Arrow' - namely, the discovery of Data's head found miles beneath San Fransisco - that has our resident android pondering his own mortality. IT also consumes those around him in a philosophical melancholic struggle over losing a close friend. Eventually, the crew gets down to the business of why that head was there and the time travel aspect is where things begin to stall. Data in the 1890s, especially. Guinan's presence there seems a bit forced, although Mark Twain's scenery chewing is an amusement. Tightened up, this could've been a good episode; but a cliffhanger?
