I think it was among the greatest movies I've ever seen. It was not only a zombie movie, but also had a deep storyline. And Will Smith is the greatest actor alive.
The movie was pretty good, but it was kind of random how he just randomly found a hand grenade in his drawer. It could have at least shown him putting it in there earlier in the movie. Also, I believe this has been mentioned somewhere earlier in this forum.
I thought it was bad. The first half was good but the second half was badly edited and written. Some of it didnt make sense and there was a lack of continuity
