Following on from the last point, Lazarus Pits need to not be a thing in the DC universe. For those who dont know, a Lazarus Pit is a pool of chemicals, similar to those found at any top-class spa resort, which have miraculous curative powers for all who bathe in them. Theyve kept Ras al Ghul, the leader of the League of Shadows last seen in Nolans Batman trilogy, alive for centuries, and can even bring people back from the dead. Its not called a Lazarus pit for nothing. There are a few reasons we shouldnt see a Lazarus Pit in the DCU. Firstly, theyre closely associated with the League of Shadows, who formed the backbone of Nolans Dark Knight Trilogy, and to have them turn up again in a new guise to face a new Batman would be total folly. The second is that although we dont know what sort of tone the DCU will be going for, it should hopefully be darker than Marvels more breezy efforts. To that end DC really need to make sucker-punches like character deaths stick when it decides to start culling the cast or the actors contracts expire and a Lazarus Pit would rob any film it appears in of suspense. Its Chekhovs Gun but instead of telling you something awful is coming its telling you not to worry, that everything will be fine. That shouldnt be an automatic assumption, especially when it comes to DC.
