I think it's very hard to talk about these characters in a closed-ended, sort of non-sequel way, especially characters like The Flash and Green Lantern, which have such rich, long histories.
Time management is really key for me.
'The Sixth Sense' was a very enjoyable, successful movie despite the fact that there were plenty of people, including myself, who saw the ending coming.
Fortunately, the DC Universe is full enough and replete enough with every kind of character that you could want, that it's not that hard to find the right character. Sometimes it's nothing more than an Easter egg, or a name drop, and sometimes it's someone like 'Deathstroke,' who is a huge part of the DC Universe.
On 'Arrow,' we have Ray Palmer and Roy Harper, and if you call Roy 'Ray' and Ray 'Roy,' you have to put money into the jar.
If Hollywood is going to keep going, the writers need to be creatively fulfilled by creating their own things. We need to generate new ideas, so we're not always cannibalizing old ones.
