No, they don't, but i prefer when they have an ending. Having a film end open-ended seems so unsatisfying. I know some people can appreciate it, but i prefer a conclusion.
I'm surprised the replies so far says it doesn't necessary needs a happy ending. I totally agree with that.
But seem as
@odog posted, it seems to translate to profit making. Most people still wants a nice and neat happy ending that explains all. Reason why alot of popcorn flicks makes alot of money as well.
I like GREAT films that have open ended endings. Under the condition that the film already has an excellent plot initially, not just crappy ones but ends suddenly confusing audiences. The good ones let viewers imaginations decides the fate of the character we got invested in by the 90mins to 120mins end.
So many people hated Inception, a large number because of it's ending I might add.
At least in the theater I watched, all of us went.. Ohhh? while gasping. It broke the internet with discussion if he was in the real world or not. It was a masterpiece ending imo.
Another is 2013 Prisoners. When Gyllenhaal turned after hearing the faint sound of the whistle but cuts to black. Did he really go to investigate and save Jackman's character? Or did he shrug it off? There was a thread here few years ago where another Mayberrian was in a heated debate with me that he was saved. I told him, it's up to individual interpretation. Imo, he wasn't.
That's a good ending imo. Makes people discuss/argue even after leaving the theater. I personally don't like popcorn flicks but understand why they do so well in box office.
