Happy & Simple ending অথবা Sad & Dramatic ending?

I'm going to write a final season for the প্রদর্শনী Heroes. It doesn't matter if আপনি watch the প্রদর্শনী অথবা not, can আপনি tell me what kind of ending you'd want to a show? The happy one is typically what you'd expect and turns out good for pretty much everyone and the sad one is just extremely dramatic and epic with a bittersweet resolution.
Any suggestions are appreciated! :D
