"The Birds" is an amazing classic that focuses on Bodega Bay being attacked by countless birds for unknown reasons. Side plots involve around a woman and a man falling in love but his mother not accepting her.
The movie is great at creating terror. The characters are in a desperate situation, they don't know how to deal with the problem, since they don't the reason the birds attack. This movie was intense in the 60s, and so it is nowadays. There is no music used, what makes it feel more real.
On the other hand, all the bird sound effects are created with a synthesizer, which was revolutionary.
Like in all Hitchcock movies, the cinematography is perfect. Especially the bird-sight scene and the last few shots of the yard.
From the beginning to the end this movie is a masterpiece.
The movie's violence is nearly nothing at nowaday's standards but it was very strong for the 60s.
The birds attack people and leave bloody gashes.
A corpse is found with its eyes gone, the room is covered in blood and feathers - may make some people jump, but no music is heard in that scene. Tweens won't be affected by it nowadays.
(End of SPOILERS).
Nowadays this is not a big deal, but at that time it is one of the most violent movies i have seen from that time. Suitable for viewers 12 and up.
