Half of the movie

We watched a movie last night. The first half of the movie was really interesting, but then the last half of the movie made us mad.  That's because the last half was only what he saw in the future but didn't really happen.  Then, they cut back to the present and ended the movie without showing us how the plot lines with the terrorists and their relationship ended.  So, we would recommend to only watch the first half , then stop watching the movie.
