They should either move forward or start over altogether. Lets look at some glitches that happened because of going halfway:
- Wonder Girl is an established veteran hero, whereas the person who was suppose to be her mentor is a newbie.
- Silver Age Hawkman existed Post-Crisis because of no immediate plans to reboot him. Several years later, a reboot is not only done, but all of Silver Age Hawkman's Post-Crisis appearances are all gone.
Big example is Superboy and The Legion:
- Clark Kent wasn't Superboy, so a Pocket Universe is established to explain why the Legion was inspired by him and even met him frequently. Maybe not perfect, but satisfying.
- Later on, the Legion of Super Heroes is rebooted, thus no longer needing to keep the Superboy/Superman connection, so the Pocket Universe can be removed. Except, that the then current Supergirl originated from there, plus after killing the Phantom Zone criminals, Superman exiled himself into space and met The Eradicator, who was important to The Return of Superman. So we can't get rid of the Pocket Universe afterall.
Deadpool on the "genius" of Hollywood: Everything's turned into a movie these days. -- Old TV shows, board games, candy bars. And let me tell ya, I'm totally stoked for Butterfinger The Movie.
