Leon: The Professional
Honestly one of the best movies I've seen in quite some time. A witty and fashionable main character (Mathilda) who's only 12 years old. When her family is murdered by a "business man" and his colleagues, because her father was a drug dealer and got killed over "business" complications. She befriends neighbor and hit man Leon, who takes her in, in a "Bonnie and Clyde"-esque way.
You could say it's a love story, more of a father daughter type thing. The movie was maid in 1994, thus the combat boots and "grunge-ish" look the young Natalie Portman sports.
Mathilda is a really big fashion inspiration, mainly on tumblr, and that the 90's style is booming right now, she is more in the spot light then ever.
Besides the both lovable characters, the plot is great, it's never boring and overall I am in love with this movie, and Leon is adorable... I highly suggest watching this, you could watch it on youtube if you try hard enough to find it, or you can rent it on Netflix.
