We watched "Flightplan" over the weekend (I really need to get our password to Netflix from my wife)
On the upside it was an actual 90 minute movie. No long drawn out ending (well not really) matter of fact no long drawn out explanation either....and thats where the downside begins and ends.
I don't want to give away SPOILERS but you think you have it figured out and then 20 minutes later ......well lets just say not so much. What makes this possible is a set of events so perilessly balanced that getting caught at one stoplight or old lady crossing the street could very well have screwed up the whole plan. The Flightplan that is.
I have to say that as the final upside I learned way more about an airliner than I ever dreamt I would know and probably more than I should.
