Last 2 episodes have been mostly trash with a few nice bits added. The pros of this episode were the scenes involving Data/Lore, and seeing the whole crew sitting together again. Everything else was terrible. The duration of the Jack mystery box has gone beyond frustrating now. Typical of Nu Trek to include a mystery box in almost every season, and in almost every instance the conclusion is an anticlimax. I expect no different this time.
And thank goodness for the end of Vadic. Seriously, how is such a campy, cartoonish, moustache-twirling villain like this endearing to anyone? She was absolutely ridiculous. Reminds me of the Chaotica hologram from Voyager only not remotely as entertaining and unlike the hologram, Vadic is supposed to be a serious villain.
By the way, have the writers heard of Laas the Changeling from DS9? Because he could survive in outer space. Guess Vadic missed that class in the Great Link.
