Watching Hayden Christensen "act" in Jumper is like repeatedly stabbing yourself in the eye with a #4 pencil.The film itself was decidedly 2.5 star-ish - nice looking special effects, a story that could have been a lot better than it actually was, and a phoned-in performance by Samuel Jackson that, unfortunately, seems to be the norm for him these days.Nothing, however, can prepare you for the agony that Mr. Christensen's thespian abilities will cause you - I mean, people say that Keanu Reeves is bad, but Keanu is a regular Kenneth Branagh (or Emma Thompson, if you prefer) compared to the atrocity that is Hayden Christensen. He was awful in the Star Wars movies, and yet ... here he is even worse.So, thank you, George Lucas - thank you very much for unleashing this beast upon an unsuspecting world. I mean, wasn't Jar Jar Binks enough?
