I finally saw this today. While there really wasn't anything in the way of stuff popping out of the screen the sense of depth was very visible for a post-conversion. The director obviously had 3D in mind when framing the shots, placing objects in the foreground and generally keeping the camera fixed for many shots. As such most scenes, even the darker ones, have a nice separation of foreground to background objects. Ghosting was also pretty much a non-factor on my 2010 Samsung plasma.
In terms of the film itself, I found it entertaining and it had some good performances but I didn't think it was a well paced as other recent films from the same genre. It clearly tries to ape the 300 aesthetic but never quite manages to attain that movie's visual flair. The sets are also fairly simplistic and its kind of obvious that the budget was a limiting factor. Still, definitely worth a viewing and one of the better post-conversions released yet.
