The Interpreter and Cock Blocking

So I saw the Interpreter a couple of weeks ago when it came out and it was really good. It seems as if it has not really gotten much attention since it came out though which is too bad. Sidney Pollack really knows how to make a thriller, especially when it is staring Nicole Kidman and Sean Penn. I also saw Sahara when it came out and it was quite bad. The Interpreter was the complete opposite of that movie. Both movies to start out with some action going on. Sahara's action is completely pointless and never really ties in with the rest of the movie, whereas in the Interpreter the opening scene has a very important part to play in the whole film. There was also some unexpected humor in the movie. It was really odd because Sean Penn looks and acts pretty sad and lonely and then he cracks a joke and the audience can laugh for a second and then the movie pulls you right back into the suspense. This is not really a complete review but I really like the movie so don't overlook it as all these other flashy movies start comming out.
Now on to the Cock Blocking. So I have a question. Do think it is right to stop some chick with getting with another guy even if you don't have any intentions of your own? Is Cock Blocking acceptible in the Guy Code? I just learnt what it was like a month ago and I don't really know what to think of it. So if you have any answers please comment.
