For its production standards not a bad product.
Some of the decent second tier horror and zombie movies were made in the 2015 and this is one of that. When the actors are in demand, we expect big from their movies, but this story suits for these actors. Because an average story looks better with guys are not in the watch-out list. So I was not surprised with the movie, but enjoyed the entertainment it offered.
Rainn Wilson's the man of the movie, but as for the narration Elijah Woods stands on the front. In this, the children were the antagonist, but it is an R rated movie and nothing was so serious to consider. You know bashing kids kind of stuffs were carefully crafted. Comedy means not like you're going to get the loud ones, but simply acceptable for a change in the storytelling.
If you exclude the zombie kids, the rest of the movie was nothing new. The same old adventure with the similar group of people who tries to survive the epidemic. Especially how it all begins was not logical, so you better not look for a proper explanation for those things. Even the runtime was well shorter than the 90 minutes that makes it sweet, Overall a fun movie, only if you accept what it delivers than what you want.
