Terminator Salvation (spoilers)

I finally got around to seeing the new terminator and I liked it better than most of the reviewers seemed to. One thing that annoys the hell out of me is some of the postings I've seen about the film on various online forums. Several different people were complaining how easy it was for Conner and Marcus to infiltrate the Skynet compound at the films climax. I watched the film prepared to be disappointed by this and HELLO! Skynet LET them in in order to trap them! It was not a minor plot point. Hell, the computer even explains it to Conner at the end of the movie. How freaking stupid are people? I think I'm beginning to agree with those who say that people should have to pass an intelligence test before being allowed to post on the internet.
