I thought I posted this earlier but don't see it now, if you saw this before I apologize.
I rented this the other day and thought it was OK but I didn't really get anything that felt really unique to the Dredd property and not some other future action movie like Lockout or the Total Recall remake (the violence and slomo was stylish but not necessarily "Dredd"). Taking this movie strictly on its own terms I don't know that there's more to explore. Sure Dredd didn't take his helmet off but why?
The old Dredd had Rob Schneider but it seemed to do a better job showing the world of the Judges. I'm curious to watch that again, it's been a lo-o-ong time, and compare.
