1. These Are The Voyages... (Star Trek: Enterprise)
These Are The Voyages... had so many issues that it's difficult to list them all. The premise itself was OK the final adventure of the Enterprise NX-01 is watched on the holodeck of the Enterprise-D. But it was riddled with problems. The romance between T'Pol and Trip which had been built up for two years was totally brushed aside. Despite the course of several years having passed since the previous episode, the entire Enterprise crew (and the ship for that matter) looked exactly the same. Plus both Jonathan Frakes and Marina Sirtis are simply a great deal older than during The Pegasus the episode that the holodeck scenes were meant to be during. It isn't their fault, and in fact Brent Spiner didn't appear in person as Data as he thought he was too old for the part at the time. Plus you have the matter of Trip's death which was just plain stupid, to the extent that they've tried to rectify it in the novelizations following the end of the series. All in all, the episode is just a silly way to force some TNG into Enterprise, and Rick Berman and Brannon Braga should be ashamed. It's not just the worst crossover episode, but a contender for the worst episode of the franchise, period. Join us next time as we continue to count down the crossover episodes of Star Trek, as we hit the top 10. There's plenty of quality episodes to count yet - Trials and Tribble-ations, Timeless and Unification just to name a few.
