I saw EXODUS 3d yesterday. It was the first non-animated 3d I've seen so far. Before that there were only Avatar (which was bad because I arrieved late and had to sit in the very front, 3d effect didn't work great there) and one of the Ice Age movies.
Yesterday I ended up all the way back, wich wasn't the best choice either, because it made the whole thing feel like I'm looking through a window behind which the 3d action takes place. For close ups in action scenes it felt a little blurry and uncomfortable to bear, but only slightly so. For some normal short - med distance shots there wasn't much of a difference, IMO. For the grand totals, showing the landscape and overall setting, getting a feeling for the whole place, it was pretty good, though. Generally I seem to get along pretty well with that 3d stuff.
On the movie, even though it's a rather lengthy film, I had the impression that it jumps from event to event at some points, just to cover it all. It almost kind of requires the watcher to be familiar with the story to arrange all the events. And, even though I'm not too familiar with the storyline, I had a feeling the movie made it's own interpretation at times. In a way I couldn't follow that well.
