Technically this episode is a hold over from season one, but serves quite well as starter for the next season. Worth the wait if you watched it back in 1995.
Story wise, this episode tackles a cryogenics angle in a way that totally puts to shame "Neutral Zone" from STTNG. Where the latter drags with it's irrelevant and hollow characters and seems to go nowhere. On the other hand, "The 37's" captures your interest from the start with the ancient car and airplane being discovered, and keeps it there by using real characters from our history; in this case Ameila Earhart. The use of a real character and the fact that this character's disappearence from Earth still generates questions and speculation keeps you hooked to find out how the writers would explain the disappearence in the Star Trek universe.
A interesting question to think about is whether people from our time would choose to stay behind on a new planet serving as a substitute Earth or whether they would consider it a streak of luck beyond counting to be able to live a lifestyle with technology and opportunities that they could have never dreamed of in their lifetimes.
A major standout of the episode is getting to see Voyager itself actually enter the planet's atmosphere and make a landing. Definetly a first in the feat itself (besides Generations crash landing)and it is different to see daylight through the ship's windows during interior shots.
