Frodo deserves his praise at the ceremony, however there is some validity to this.

He claimed the ring, and Middle Earth is forever ruined for him. They go back to the Shire, kick ass, kill a bunch of bandits, and purge Saruman from their home, and save everyone. But Frodo literally can’t even enjoy it. Middle Earth is forever ruined for him, and he literally has to leave the content and metaphorically pass on to the next world in order to achieve any semblance of peace. His soul is thoroughly shredded from the ring.

Anybody that says LOTR has a cliche ending where the good guys win is a moron.
