Critics have a different way of seeing films, dude. Not like us. They're more experienced with films, they study screenplays, & background histories.
I can see why she was nominated. & trust me, that's not her real personality. That's totally Juno, not Ellen. To think, a teenager like her, her cute personality, in fact someone like her, gets pregnant at a critical age. The film shows how she deals with the situation, & it's a moral for all pregnant teens out there, it's kinda sending a message. Not all films sends the right exact message, Juno was highly acclaimed.
Dude, I felt the same way about Little Miss Sunshine (2006). I wanted to see why it won 2 or 3 Oscars. People thought it was nothing special, just like Juno. But you're not seeing hard enough. Take a look at the powerful screenplay. Olive Hoover, who has a chance being Little Miss Sunshine, a beauty contest, when she's a symbol, already a sunshine in her dysfunctional family. "Why did you try to kill yourself, Uncle Frank? That's just silly". The exact words a suicidal person is suppose to hear. When her brother found out he was color-blinded, who was next to him, saying absolutely nothing, but just a hug..? The little girl. When she was asked if she dances well, she said it with so much confidence--"Yes, I'm definitely pretty good. Yeah, I am", when we see in the film, she doesn't dance very well. But that doesn't matter, that's confidence. That's the message the film is bringing us upon ourselves. When Dwayne is color blinded, he can't go to the Air-force Academy, a dream he's had his whole life. He just says "F*ck Beauty Contests. Life is one f*cking beauty contest after another. High School, college, then work? F*ck that. If I wanna fly, I'll find a way to fly. Just do what you love...& f*ck the rest". What kind of message does that bring to the audience? Follow your dreams, despite the speed bumps going through it. & in the beauty contest, every girl were dolled up & splattered with makeup on, Olive stepped up as herself, her natural beauty. Now I can see why it was Oscar worthy, the screenplay was a great piece of work, I'm glad it won the Oscar.
You gotta see the same way for Juno. There are probably more films you believe is a piece of sh*t of winning, but try to look into it. See what films have hidden messages, & try to look at it the way critics do. I do agree, they pick some of the most stupidest movies, like Gladiator (2000) or Crash (2005). Just keep watching Oscar nominated films, find that message.
my dad taught me how to watch movies very well when I was a kid, he was a theater director.
