Time travel episodes usually are annoying because they depend on logically impossible cyclical relations, as this one does. However, given that violation of logic, this episode does a good job of remaining logically consistent within its particular logically impossible structure, so it is entertaining and draws the viewer in to wonder what comes next.
One thing, though, seems inexplicable. Where did Deanna pick up such a great tan between the end of Part 1 and the beginning of Part 2? Compare her appearance at 8:45 in Part 1 with her appearance at 30:25 or 35:30 in Part 2. There seems to be a time gap in the plot where unexplained events transpire. Harrumph. Well, maybe it's just the effect of waves on Betazoid melanin. Harrumph.
