9. Terminator Salvation
Terminator Salvation's very existence negates the point of the franchise, and for that reason, it ultimately fails as a Terminator movie. After all, the saga was about the fight to prevent the war because it offered more interesting character journeys than the war itself, so fans and critics understandably questioned the decision to follow up on T3's controversial ending by having a full film set in the future war.
Some felt it offered none of the heart that its predecessors did while others thught the lack of Arnold Schwarzenegger left it without meaning.
Now while all of those aforementioned critiques are actually true, the film made a case for its own existence and whether or not that existence should be in the Terminator franchise is still up for debate, but the fact of the matter is that Terminator Salvation is actually a pretty solid war film - one that is worth far more than the mediocre 33% score on Rotten Tomatoes.
The film is heavy on thrills and, for the most part, it expands on the terror that the previous three films could only ever allude to. Meanwhile, Christian Bale is a decent John Connor and the film features an incredible performance from the late, great Anton Yelchin who channeled a surprisingly authentic Kyle Reese.
It's may not be a great Terminator film, but Salvation is still a pretty good movie in its own right.
