A hit film franchise should leave you wanting more and not overstay it's welcome. This is why people loved the first Star Wars trilogy of the saga and have been very critical of the ones made since. The Back To The Future franchise got it right when they gave us a great trilogy and have resolutely left it at that. Katniss's story will have been told and that's where it should end. Hollywood needs to learn not to run a good franchise into the ground.
