I'll be honest, I don't usually watch a lot of virus infection films. But of the few I've seen, Contagion falls short. Unlike other films of this genre, Contagion leaves you on the outside of the story. You don't really hate or love any characters. You don't really connect with anyone, not to mention at times my mind was wandering because this film runs too slow, plus certain things didn't keep to being realistic. The bus and people on it would have been quarantined. Not worth going to the theater to see. To be honest, I wouldn't even rent it, or pay to rent it. Borrow it from the library or wait till it comes to television. Not worth any $, to see it.
Feeling like a virus film : Outbreak, Andromeda strain original or sci-fi ( sy-fy) mini-series. Want a horror twist to it, 28 Days Later, is really good.
