The first season and this one has re-introduced me to a side to the show I had forgotten was there, mainly the top-quality cast and guest stars. Though I love original Trek, I think that Voyage's cast was actually more talented. They just weren't given the material they deserved. Richard Basehart has always been a favorite of mine, and his Admiral Nelson is the kind of dedicated, dynamic warrior-scientist we wish actually patrolled the seas keeping us safe from everything from enemy super-weapons to natural disasters and even alien invasions through his yankee ingenuity. David Hedison in contrast plays well off of Basehart with a tasteful restraint and Bob Dowdell is absolutely convincing (and excellently cast) as the ever-reliable XO, Chip Morton. 'Ski, Sharkey, Reilly and the low-key Patterson all interact smoothly and I think the outlandish scripts of this season actually served to bring out their best. In the episode "the Shape of Doom", the heartfelt plea of the whale hunter to Nelson in his quarters may be the single most stand-out moment of this collection (a scene which is sadly wasted on an episode that merely rehashes "Jonah and the Whale" from season one). The FX, as usual, is a mixture of awesome even by today's standards (the "master" shots of the Seaview, etc.) and the cheesy FX which were limited by the budgets of the individual episodes for which they were shot. And I'm sorry to all those who hang their hats on the "serious" episodes, but '60s sci-fi is very dated today, and Irwin Allen's spastic thought processes accidentally led to this show still being watcheable now as a kind of grade B adventure with great production values. The monsters are a hoot and are some of the best in the series. But yes, towards the end of this set, the drastic drop in quality is impossible to ignore when one compares the rather thoughtful "Graveyard of Fear" to the 2-dimensional, ludicrous "the Men-Fish". In later seasons, Basehart would appear to be constantly frustrated while Hedison would seem just plain bored. Notice, too, how in the monster episodes the monsters themselves are relegated to being the sub-plot (no pun intended)! But the majority of the episodes hold up and this set is perhaps the highpoint of the show. Although there would be some good episodes in the last 2 seasons, the show would never again be as consistently good (the aforementioned "Shape of Doom" hints at the graveyard of stock-footage to come). Awful scripts that wouldn't even make a pretense of good writing would be so numerous as to drown the few good ones in their midst.
