I think you need to read the books to "get" the premise here.

If an adaptation of a book can't be enjoyed or understood without reading the book first, then it fails as anything other than fan service. It's the filmmakers' job to get us to understand the characters and premise, and it sounds like they failed here.

Freedom of speech is not freedom from criticism or consequences. Having said that, I think that her choice of movies is what's killing her career, not some stupid comments from several years ago.

Daniel Sunjata is in it, therefore I won't see it. It's that simple.

Nah, Alien: Resurrection did that. Alien 3 was actually a pretty good movie, it just wasn't what people wanted to see from the franchise: they expected huge Aliens vs Marines battles on an infested Earth, and got one Alien running through tunnels picking off guys at random. It felt like a step backwards. But anyway, the plot and setting weren't Fincher's decision.

Fight Club, on the other hand was a boring, pretentious, stupid piece of crap. Its popularity has always mystified me.

He couldn't have voted for Reagan even if he wanted to, he wasn't a citizen.

Are you even reading my comments? I actually said three comments ago:

If you really can't find an actress who looks the part, forget about hand-to-hand combat altogether and just have her shoot everybody.

And, since you seem to have forgotten, you set the parameters with your first comment:

Martial arts training alone doesn't make for a compelling action hero/heroine. You can't turn an uncharismatic actress into a star, but you can teach a charismatic actress enough to make her look believable.

You were quite clearly talking about hand-to-hand combat, as you were when you said:

By believable I meant that her moves look believable.

But apparently what you really meant was 'she manages to kill the bad guys in some way'. OK, whatever.

OK, how are you going to have an action movie with a heroine that can only fight small, weak adversaries? What scenario could possibly work?

We are both talking about action movies, aren't we? An action movie without big, strong badguys? Seriously?

Would you cast Michael Cera as James Bond? No of course you wouldn't. It's the same if your action hero is a woman, she has to look the part.

No, but it's necessary to have a heroine who looks like she could realistically beat a 300lb strongman. Unless, that is, she's supposed to be 'magic' or have 'superpowers', in which case the whole thing is moot. If you really can't find an actress who looks the part, forget about hand-to-hand combat altogether and just have her shoot everybody.

If the actress doesn't look believable in the role, it isn't really anything that scripting or fight choreography can fix.
