West Side Story (1961)

Again, the plot line is simple. Girl sees boy and the two instantly fall in love. Too bad that they are from different backgrounds and can't be together.
Maria (Natalie Wood) is new to America but Tony (Richard Beymer) was born there. They meet at a dance but Maria is Puerto Rican while Tony is Polish. Each of them have the support of their every own gang (not really, but in theory). At least Tony went straight and got a real job while the rest of them just roam the streets, picking on each other.
The rumble gets out of control and one from each side dies so Tony and Maria must get away but the message gets jumbled so Tony winds up dead to.
Now, while the plot is simple, the choreography and singing is not. The main reasons to turn out for the film is the dancing and score as the dialogue is pitiful at times, such as when Tony declares that he loves Maria, she just says yes and their meet-cute dialogue is atrocious. But the songs are so memorable that you can almost forget some of the weak parts and Rita Moreno is just brilliant as Anita, Maria's friend and almost sister-in-law. She fully deserved her Oscar. Natalie Wood does her best as Maria though she's not even remotely Puerto Rican, she's Russian, but she owns the last scene, scolding everyone for picking hate over love and friendship. It's a shame that so much bloodshed occurred all because two people fell in love. Grade: A-
Side Notes:
-Russ Tamblyn and George Chakiris give solid supporting performances as Riff and Bernardo who both meet tragic ends. But I found Ned Glass's Doc (who owns the drug store) to give the most effective performance in the film (other than the utterly brilliant Rita Moreno).
-For the 'wedding' scene, both Tony and Maria get wedding rings.
-Men are truly pigs as they assault Anita even though she's just trying to help.
-The end credits are unique, something that is commonplace now but not in 1961.
-Despite being a small character, Anybodys (Susan Oakes) plays an important role about breaking the gender mold and a whole paper could be written on her character alone.
