Go see 'V for Vendetta'.
Don't read reviews, don't investigate who's in the movie, don't read up on it.
Just go see it and let the fun of wondering who's behind it all put you in league with the characters of the film.

The guys who made the Matrix movies delivered this. It's not Matrix, but if you liked the premise of the first Matrix, you will enjoy V. Great acting, wonderful vibe of "what's coming next?" throughout, and the Matrix-ey message of empowering people to not fear challenging the world they're handed by the powers that be in charge.

A great line that reflects the main theme: "People should not fear their government, the government should fear it's people."

It's a smart, engaging, sophisticated ride. Portman is great in it. The masked character is master class acting - like Boba Fett doing Shakespeare. So fun.

Don't ruin it and read who's in the movie. Just go see it and enjoy.
