The opening scene is the best and most genre-fitting part of the movie. It is what you expect from Saw, and it has some amount plausibility. After the title card drops, this movie begins to drag terribly, and become a dull mess. It doesn’t help that the movie, despite being provide the exact circumstance to do so, never actually ends up saying anything around its context.
The best part being Rock and Jackson’s interactions. Rock was never laugh out loud hilarious, but him and Jackson seemed to be the ones having the most fun on set.
