T4s director, “McG”, is currently one of the worst (and poorest named) directors in hollywood. He is also one of the most overpaid, hence T4 having some big named actors in its cast, but even that cant save this movie being trash- although some people seem to think so. You only need to watch rubbish such as McGs remake of Charlies Angels (unfortunately his best movie to date) to work out his directing abilities. If you google up the latest James Cameron interviews, even Cameron admits that he enjoyed T3, but prefers not to comment on T4 Salvation. To top things off, its not just bad luck with movie websites such as Rotten Tomatoes giving T4 Salvation an overall score from multiple sources of 30 percent either (compared to T3 which has a far more respectable 70 percent)!
