Movie reviews are more or less subjective opinion. The critics are angry old men who aren't the intended audience for a lot of those low reviewed audience pleasers.
Game reviews are a mix of subjective as well as objective opinion. Good reviewers use more of the latter. Game reviewers are usually young people in tune with the gaming audience.
Declassified, objectively, is poorly made, rushed, has mediocre graphics, animation, horrible AI, is insultingly short, has loads of bugs which won't get fixed etc. It's an objectively bad game.
