Juno

I believe this movie well deserves all the praises it got...

Not only it's a beautiful movie on parenthood, but it's one of the very best "teenager movies" (Donnie Darko is one of my favorites in that genre)...
It's very well written, with witty dialogs and doesn't shy away from its subject.
Sex, abortion, adoption can be quite heavy themes, but the movie confronts them through Juno's point of view, which is very forward and honest. Genuine.

Each member of the cast cast is incredible whether Ellen Page, Michael Cera, Jennifer Garner, Jason Bateman, Mark Loring, Allison Janney or J.K. Simmons, they all inhabit their characters perfectly and deserve the highest praises. They hold the film on their shoulders.

It's a straightforward film that go straight for your heart and takes it.
I mean, Juno is like, so cool!
