I don't precisely know how many people loved him. but Frodo Baggins, (in the movies at least) despite it having been on my to-do list for years I still haven't actually READ Lord of the Rings, but I recently re-watched the movies, and just wanted to smack Frodo in the face
for starters, he's constantly praised for being resiliant to the ring, now a little bit of perspective.
Bilbo carried that ring for 60 YEARS, and still managed to let go when the time came (albeit with a little nudge from Gandalf) Frodo had it for about a year, and when the time came to destroy it, "the ring is mine!" you dick, you deserved to get your finger bitten off, there is no way he didn't know that the ring would never answer to him, and once he put it on, everyone in Mordor knew where he was, what was he hoping to accomplish?
that and the falling into the marshes for no reason bit, Bilbo was a much better protagonist I thought, but maybe I'll feel differently when I get around to reading the books, maybe get a little more perspective on it
