If you're somewhat of an aviation person, you'd know and find it hilarious for the aircraft to be called the A390 - especially coming from China. However, the effort to make the aircraft look as modernised and futuristic as ever is commendable. The plot, just like in Flight From Hell is a well-planned, and not as predictable though you would still be confused at the low-effort in the second half of the movie involving an emergency landing and the very same plot device from FFH - the mysterious force, which somehow comes onboard the aircraft and as usual, starts terrorising everyone onboard.
What I don't get about the second half is the sudden introduction of some people who apparently aren't who they appear to be - it contributed little to the development of the plot and the movie ended in much disaster. On the same topic of plot, having a "hero" installed using an excuse was a genius move to act as the counterbalance to the people who weren't who they said they were.
