Honestly, I can't even remember all the films that I have watched that have included zombies. The only one that I can think of that I enjoyed was World War Z.
A friend showed me this recently and I quite enjoyed it, I agree its storytelling was pretty good, it got quite emotional at the end.I cannot say that I really love Train to Busan but I like the plot. It is a poignant story of the father and daughter with the zombie as the backdrop.
