You're not likely to be frightened by MONSTER THAT CHALLENGED THE WORLD, but as 1950s sci-fi/horror programmers go it is better than most. The story, which resembles everything from THEM! to THE THING to BLACK LAGOON, concerns prehistoric eggs that are irradiated by atomic blast and then released by earthquake into a saltwater sea by a military station--where several military men go missing as a result.
The cast, script, story, and monster are all okay but nothing special and never rise above the "B Movie" level, but the movie is an enjoyable way to spend a rainy evening. It's also mild enough for use as a "family night" film with older kids, and would be a good way to introduce them to the genre without giving them fits; younger kids, however, will either be bored or genuinely frightened, so you might want to prescreen it just in case.
