Steve Grzesiak’s review:
Even by the standard of some Asian horror films in the last 20 years or so, Infection stands out as one of the craziest of them all.
Set in a decrepit hospital seemingly on the verge of being shut down for good (once you see what the staff are like, you can see why), this initially feels a bit like Assault On Precinct 13 in the way it's about some reluctant souls being left to look after a deserted facility. And then the carnage begins.
There is a feeling here that the makers of this film are throwing a little bit of everything at this one - it's at various points a ghost story, there are echoes of a zombie film, and it also has straight-out gore movie moments as well not to mention the Asian staples of spooky female ghouls and strange stuff going on with mirrors.
Strangely, despite a demented ending that makes almost no sense, it actually works. It's all so utterly barmy that you can't help but enjoy it, even if what is actually going on does have a tendency to elude you for stretches of the film. Pretty good fun, just don't expect it to make sense.
