Dredd 3D

If your only exposure to Judge Dredd is the 1995 version with Sylvester Stallone, then you're in for a real shock with "Dredd 3D".
This version abandons all the giant robots and flying motorcycles and brings Dredd to a grittier more realistic world.  Admittedly, still not quite the same as the comics.  The comics were really a mix of both Dredd movies.  This version is about as close as you can get without starting to look like "Blade Runner".

Olivia Thirlby is better than Rob Schneider in every way. 

The plot is very simple Dredd and Judge trainee Anderson go to the Peachtree apartment complex to investigate a murder.  While there they bust a drug operation run by Ma-Ma played by Lena Headey. 

Seriously, don't fuck with her. 

 Ma-Ma locks down the building, all 250 floors of it, and announces it won't be opened until the Judges are both dead.  Dredd and Anderson have to escape Ma-Ma's goons and the apartment residents who want them dead. 
Removing the wild science fiction elements helped make Dredd more accessible, but it also made it more generic.  The plot was so simple that you could put just about any set of  characters into it.   This could have easily been a Robocop film, or a Jason Statham film. 

While "Dredd 3D" is a great action film, it just doesn't do much to distinguish its self from other action movies. 

and no, he never takes off the helmet.
