DC's misstep was ****ing up an already proven model by MCU. 1. Have an actual plan, which shouldn't be too hard, since it's all laid out in the comics. 2. Make individual character movies that are supposed to be tied to together. Man of Steel was not initially intended to be tied together with anything. It was supposed to be the start of a Superman reboot. 3. Use those individual movies to have all of the characters join together. 4. Profit. Batman never even got a stand-alone movie in the DCU, which is criminal. Aquaman, Cyborg, Flash, and Wonder Woman made their appearances in the movies that didn't even feature them. They ****ed it up so badly, and the blueprint was already done for them.
