Hmm.
A film about a scientist who is randomly attacked by a load of future police, befriends a random security guard who gives him a crow bar, and is then followed on a long and boring journey through some canals where we find he has unusually good weapon talents for a scientist, until he eventually befriends a random woman and they then get blown up together.
And for some obscure reason, there are zombies.
Half Life 2 = worst film ever.
