The fourth film in the 25-year-old Terminator franchise is easily the worst. Christian Bale stars as John Connor, a leader in the resistance against the machines that wiped out most of humanity at the end of Terminator 3. Sam Worthington offers an amusing performance as Marcus Wright, an ex-con who donates his body to science and awakens to a mighty big surprise. The beginning and ending of McG’s film are so awful that they take the air out of the middle part. It’s a good-looking movie with a decent action sequence here and there. But the dialogue is often dreadful, and it would be a good idea to jettison the writers and director for the next installment. This franchise needs yet another fresh start.
