Why Can't I Be Open To My Parents?

For those who feel the same, come sit next to me.

Me and my parents.
We're not really open to each other. I want us to be like friends, like those cool parents from the movies, where we can talk about anything. But they can't. Or they wont. I know that i shouldn't compare my parents to others, but i really want us to be close.
 
I do want to talk about everything to them, my school, my life, my friends, my love life, everything. But i just feel like they're so judgmental and so.....parents. That's why i don't really talk a lot to them.
I just feel, it is so hard to be open and talk to them.

I had a few close friends to talk to. I feel more easy to talk to them than my parents because, well, they're my friends. They do judge sometimes, but not as judgmental as my parents. Not like my parents, i still can handle their judgment.

So, how to fix this situation?

Should i go and tell them what i want or should this thing keeps on going?
In our family, where we embrace eastern culture, democracy isn't really happening. Your opinion is legit only if they said so. If you disagree with them, then you're impolite.

Maybe freedom in eastern country is just mirage.

Help?
