Terrible
CGI is average (exlcuding the lip sync which is awful). The plot is so cliched it is a cliche. The characters/script are flat and just stupid.
It falls from one disaster to the next, with the good guys you care nothing about.
The film had a horrible habit of showing us the impending doom (ie a horde of zombies) then pulling back like it was the setup for a video game.
Then the plot is all revealed at the end just in case you couldnt follow it. Which I am glad they did because nothing made sense.
Even the Final Fantasy film (the only one people watch who havent played the games for 500 hrs) made more sense than this and this film should have been really simple.
The way it plays makes me think this was storyboarded to be a game and they decided to make a film but didnt do anything to link it together properly.
Theres no such thing as BEST EVER, just best in recent memory
