I’ve been reading the legendary E.E. “Doc” Smith‘s Lensman series recently. After Triplanetary (1948 – originally published as a serial in 1934), which really wasn’t about the Lensmen, but did introduce a few key characters, came First Lensman (1950) which still gave off more of a 1930s flavor.
While readers get their first real glimpse into the lives and power of the Lensmen, the tale reveals itself as terribly dated. The “good guys” are very “North American” centric, women don’t have minds compatible with interacting with the lens, and our guys are scrupulously honest and forthright.
As with “Triplanetary,” I sometimes found it difficult to keep track of scene changes and figure out where I was in the story from one point to the next.
Along with the purely space opera aspects, there were heavy political overtones, no doubt reflecting Smith’s actual viewpoints.
