Recently my wife signed us up for Netflix. Until then, we bought nearly all our movies rather than renting them. Well, that meant that a lot of movies that we weren't sure we wanted to buy got passed over. There were also a variety of TV shows we wanted to see from the beginning, but didn't want to invest in whole seasons if we didn't like them. Now that we've signed up for Netflix, my wife gets to watch those chick flicks that we aren't willing to buy. As for me, I get to take advantage of Netflix's enormous selection of movies to satisfy my eclectic taste in movies.
It! is one of the better '50s sci-fi movies. It's not a classic like The Day the Earth Stood Still (1951) or Forbidden Planet (1956) (whose monster also has a creative way of killing its victims), and The Creature from the Black Lagoon (1954) still features my favorite (non-Godzilla) monster, but the movie is genuinely entertaining. And the fact that the story foreshadows the plots of so many modern sci-fi/horror movies is of historical interest.
