I actually like that everything was in Katniss’s POV. It makes it clear as the series goes on that she’s suffering from massive amounts of PTSD and disassociating hard by the time the end of the series rolls around.
IMO it made the epilogue stand out from HP’s “babies ever after” epilogue- because she’s so clearly suffering and struggling throughout the last book, seeing her years after, having eked out a little corner of joy in a cruel world felt more rewarding to me
The movies had so many questionable decisions. They insisted on trying to make the president coin betrayal a surprise when her being sketchy AF and using Katniss as a propaganda figurehead with little support was a large part of Katniss’s struggles.
The insistence on shoving in a love triangle into the movies because Twilight when the political situation of the world and how it actively was a detriment to her relationships, platonic and burgeoning romances. The slow drift away in Katniss’s mind from her initial closeness with Gale and more towards Peeta as the plot continued on was (imo) much better portrayed in the books as well.
As it is, movies will inherently have a disadvantage to books when it comes to character internalizations. If the books had been in 3rd person, it largely would have been similar to the movies in missing nuanced character struggles and mental shifts
