Maybe a 6, there were just so many places in the movie that could have been written different that would have made it so much better. What is wrong with all the writers today. The plots either have an agenda or make very little sense.
I saw
Legend last night because Alvin was sold out for all of the runs. An interesting piece is that the Paramyxo virus, Measles virus, is very similar to the Canine Distemper virus. One can vaccinate a dog against Measles and it will confer immunity against canine distemper. When one sees the movie one will understand why I mention this piece of trivia. Emma Samson is the cameo in the beginning as the virologist/oncologist.
There were a lot of areas of this movie that could be improved upon, making it more believable, but overall the movie was entertaining. I did like the fact that the characters believed that God had a part in redeeming the ones that were left.
