The core concept of the movie is good. The acting is good too. The turn of events are just not interesting. Also, there is just not enough closure at the end of the movie. May be it was meant to be this way. For the second part, may be?
Weird narration in some places. 2 people in the group take off in the car. What happened to them? Also, some cliched roles. Old lady gives birth to 2 kids and then dies. Grumpy old man saves the people he initially hates. And then dies.
Sandra Bullock doesn't look like a 54 year old. That's amazing.
