VOY: "Learning Curve"
I remembered the infamous cheese going into the episode but I still burst into laughter when B'Elanna had it raced to sickbay. I think the joke should have been played up a bit more; something like that needs not be low-key. Anyway, the core of the episode -- Tuvok's training of the Maquis misfits -- is mostly rather by-the-books television. It works despite the typicality because Tim Russ really sells it. I was also rather entertained by Chakotay's "Maquis way" of setting one of them straight. I wish we got to learn more about the pasts of more than just him, though.
And with that I've finished the first season. On my way to the first full-length season shortly!
