Outer space
The theme of space is the most important and the most obvious one as all the actions take place in space. The technological innovations expose the theme of technological progress and speak for the future of machines. The element of scientific development is important for emphasizing its danger, as there is no proof that the Earth is the only inhabited planet and there might be other planets with alive creatures in the universe. People don't know whether they are or are not ready for such a meeting.
Humanity
Having awakened after so many years Ellen finds out that her daughter has died, and she, Ellen, had not given her the love. When they arrived to the planet where Ellen had met the alien their crew found there a little girl who was very scared. And then Ellen's motherly feelings woke up and she cared for this lonely girl, she treated her like her own daughter, gave her tenderness and love. Ellen's humanity, along with her strong will, makes her a character worth of following the example of.
Suppression of female rights
Ellen Ripley is a strong woman, determined and with rich inner world, but in the society of men she is not perceived seriously, constant mocks from the side of men follow her everywhere. But Ellen never pays attention to this, as her own experience with the aliens before made her stronger than any of the men. The theme of feminism is arisen to speak for women. Ripley is not believed to have met with the aliens and is often confronted with the authorities who blame her for having destroyed the spaceship. The time when the film was shot, the middle of the eighties of the last century, needed this word for women, as spoken so strongly in the face of Ellen Ripley it was to help women realize their own completeness.
