Good, stupid fun, full of unnecessary action and implausible stunts. I felt that Alex Pettyfer (who plays Alex Rider) was too bland to be sufficiently heart-throbby, but maybe that’s because I’m a) straight and b) old enough to be his father. Alicia Silverstone is still hot, even though she plays a housekeeper whose main role seems to be to shout “Alex!” repeatedly in a variety of exasperated tones. Bill Nighy is the best thing in the film, though. Worth watching just for the way he munches a biscuit.
