Jaws (1975)

One of the classic thrillers of our time. Fascinating in that it managed to build an atmosphere of suspense without constant gore or needless spring-loaded cats. Most of this movie is about the process of catching the shark, more than "OH MY GOSH IT'S A SHARK WATCH OUT!", which, honestly, is what I think makes a movie more effective. Look at Psycho. The majority of that movie was a simple murder mystery, no horror or gore... which made the few, sudden moments of terror all the more shocking. I wouldn't put Jaws on the same plane as Psycho - the in-between bits were much less interesting - but I'm glad I took the time to watch it. 3.5 stars.
