It was recommended to me by a friend and I was a bit skeptical at the beginning of it being a typical teen love story with happily ever after, but that is definitely not the case. The movie teaches us that there is more in life than just chasing our dreams of greatness to be remembered (fear of oblivion), lets put less efforts in trying to please the masses but instead concentrate on special people in our lives.
Also, we often moan about our individual life situations without realizing there other people out there with similar and worst situations. That can be used as a strength, as their individual disabilities brought them together as close friends (the scene the egg the car and try to scare the mum with their incomplete and malfunctioning body parts haha).
Finally, life is subject to entropy and decay, live the moment and when it is gone (yes because it will), don't be sad for its ending but be happy for it to have happened. One quote from the movie says don't seek wide love but instead deep love (that is deep). Recommended movie
PS: only 4 stars because I am saving my 5 for later (you will understand if you watched the movie)
