I have mixed feelings. I enjoyed the movie and would see it again. However, as mentioned above, I was afraid that, if it was a big hit, it would just inspire shitty sequels and reinforce WB's earlier thought that now every comic book movie had to be dark and gritty.
How do you pull off a sequel to Watchmen?
I don't think it would be that hard to do. It would be simple to carry on the next chapter in those people's lives.
Yep. Look at the Terminator movies. Cameron intended that T2 would be the end of the series. However, eventually they decided that enough $ could be made from a sequel and we got T3 and a "loophole" to explain how another Terminator could be around after all.
