I've been going through some old favorites of mine and wondered what they'd be like if they continued until today. Series like Psyren come to mind, which sadly got cancelled too early and still felt like it had a lot of potential to explore. Though series that ran for ages but eventually ended, like Dragon Ball, are also interesting to think about.
So here's some questions to ponder about:
Personally, Psyren and Gantz are two series I'd have really liked to see for a while longer. And I'd like to mention Berserk and Hunter x Hunter here too... while they haven't officially ended, their mini- and maxi-hiatuses are as bad if not worse, imo. T_T
