A different twist on the zombie genre with a bit of "the government is behind it!". It's fine.
And Timothy Olyphant should be in more movies.
Rewatching The Mask of Zorro (don't know how I got this idea) after so many years was truly nice. It brought back a lot of memories and also reminded how good and fun were this type of simpler, classic adventure movies. It doesn't try to reinvent the wheel and in that process tells a complete and satisfying story filled with childhood emotions and spectacle with a perfect cast.
