It's a perfectly serviceable mystery thriller, with good performances and ever stylish direction from Steven Soderbergh. However, there's nothing particularly memorable about it, and I'm already beginning to forget it. Worth watching if it's on TV one time.
Also what the Hell was Jude Law's accent supposed to be? That was awful.
Director Soderbergh is intelligent enough to really make this material work, going at it from every conceivable angle (and many inconceivable ones!) yet still giving it coherence in a decent runtime (not a Bay-esque three hours) and there's enough star power to keep one's attention. The best kind of review for these sort of films is that it leaves you thinking twice before you have an affair, or even throw out your Kleenex, and that's specifically what Soderbergh's work here does.
Contagion also succeeded in bringing out some very strong performances in a really good cast. The film doesn't focus on anyone person for too long, but dances between their stories to show the devastating spread and influence of the virus. It doesn't give the characters a lot of time to get develop or for us to get to really know them, but we spend enough time with them to understand their desperation and fear. For a film brimming with death and disease, it is surprisingly human. The people it hurts are genuine, the fear and chaos it creates is so believable and I really felt like I was part of it. Contagion was awesome.
