Surprised by high reviews. I thought the movie uneven and not very scary

Rating: 5/10 (23 June 2013)

Brad Pitt's performance was fine and I loved certain scenes and concepts (like the episode in South Korea) but overall I felt the movie was uneven and could have used a better edit. The biggest problem I had was the inclusion of some highly improbably events.
The cutbacks to Gerry's family slowed the movie down like speed bumps on a straightaway. I would have been fine with leaving them on the ship and not seeing them again until the end. Their subplot did nothing to progress the film and stopped the action at least twice. His wife's main contribution was to place an ill timed phone call that gets two men killed.
At one point Gerry drags a Israeli solider along with him for no apparent reason. Just kind of brings her along where she plays no role in the plot that couldn't be filled by an anonymous extra.
His miraculous survival of a plane crash is where my suspension of disbelief gave out. And the fact the crash occurs within wounded- walking distance of their destination didn't help.
I'm split on the "cure" for the zombie attack. It was unique and clever but Gerry's execution and test of the solution was telegraphed thirty minutes before it happened.
I did not jump once in this movie. I was never scared or on the edge of my seat. Some of the action was hard to see in 3D and one of the crucial zombies in the lab was supposed to be scary but ended up being comical, if not stupid.
I am shocked to see so many people giving this more than a C.
