It's one that I want to see for myself really. As I say, a lot of the criticism is of motion sickness. The other criticism seems to come from the same people who criticise shows like LOST because they leave some explanations to the imagination rather than spelling everything out, and because of silly little things like the battery never going flat in the camera (which, again, sounds just like "omg, why does Jack's hair never grow!!!). Which doesn't apply to my tastes anyway.
I'm not going into the film expecting a complex plot, deep characters or anything. Drew Goddard and J.J. Abrams have both said that those things were never really a focus; they just wanted to create something utterly surreal that feels real. I personally just want to see how impressive the cinematography is, more than anything else. I just want to be immersed in something ridiculous for an hour and a bit, rather than watching the usual same-old same-old hollywood drivel.
