My first reaction was... Zombies and Brad Pitt...

Rating: 8/10 (12 September 2015)

...hmm I wonder if that will work ...but I actually think it did and it did good, there are some parts of the movie that I didn't like (see below, spoiler alert), but there are many really good things and they kept me interested and entertained.
Likes, the chaos and selfishness in the beginning, the doubt and despair through out it all, the fights and survival tactics, the explosions, the viciousness of the zombies, the fast moving scenery and the locations (especially Istanbul).
Dislikes (one big spoiler), Istanbul was the greatest disappointment or the "only" weakness in the film, why do you build a giant ass wall and doesn't post any guards on top, the zombies would still have gotten in with their tactic, but it would have made it much more realistic.
