And what kind of ending you expect to see? Everyone suddenly deciding to overthrow Snow and doing it over the space of 5 minutes without any blood being shed?
No, but some
hints that Katniss had sparked a rebellion would have been nice.
Yeah, there were people rebelling earlier, but that got put down fast and was a non-issue by the end of the movie.
Look at The Fellowship of the Ring
. Frodo was still on his mission and Aragorn, Gimli and Legolas had just given themselves a new mission. You just knew that this was far from over.
THG: Katniss wins and goes home. Plot of the movie done. Nothing has changed.The end.
