Altitude is a Thriller/Horror movie that never really lives up to anything. Even if you cling to a hope that something large or satisfying will happen, you will be disappointed. This is only made worse by the fact that the acting, dialogue and plot developments do little more than to waste away an hour of the movie before the real events unfold. There is no one major flaw in this movie, however no tweaking would have made this view-able. This movie is fundamentally built around a thin plot which leads to a 20 minute series of events and it makes the whole movie seem disjointed.The plot of the movie is that a group of friends are flying to a concert and the main character in the group of 5 (Lowndes) is the amateur pilot. She offers the best moments in the movie, but even those are scarce. Errors during flight causes the plane to climb higher than intended without the ability to descend. The main cling of fear appeared to be fear of flying and the claustrophobia associated with the small cabin and uncontrollable circumstances surrounding them. However, as evidenced by the movie case, this is a monster movie though you could barely tell because it has so little face time.I am notorious for being able to sit through garbage horror movies just to see the twist or developments at the end. That being said, I waited patiently through the poor dialogue and acting. At first it seems that everything could happen to you and there is no need to suspend your disbelief as with many supernatural horrors. However, the ending and subsequently revealed underlying plot of the movie are very supernatural and unfortunately are flat and unbelievable. It really made me regret sitting through the early goings to get a stupid ending.I would not recommend this movie to anyone as it really has no redeeming qualities. The only people who might find it interesting are pilots, but for every plane focused moment, there are 3 where the physics and mechanics are awful.
