>>>I know what you mean. There seems to be so many movies lately that have such lame endings. No Country For Old Men, I Am Legend, Mist. Seems to me that it's becoming a trend...take a good starting/opening, build up the plot then completely mess it up in the final five minutes.

Sorry, that's just a bit too much for me. I must be getting soft. I would say watch it until they get on the highway then stop. I wish I had done that.
