Amazon's made some half-decent shows, so it's not completely unrealistic to imagine ...

I feel like Tom Bombadil is an interesting mystery in the universe, but they're pretty easily cut out of the story without changing anything really other than getting rid of the question of "who's this weirdo that the ring doesn't affect?" The Scouring of the Shire is also arguably cut pretty easily, and I get why a lot of people don't like it, but it seems more important to the themes in the book and to show how the heroes have evolved since they were last in the Shire.

I think Sam wouldn't have the conviction to get things done. He wasn't the one who stood up and accepted the ring at the council. Sam was loyal and didn't have lofty desires, but he didn't have the spirit of adventure and perseverance that Frodo had. He was the perfect ally to help Frodo, but he wouldn't have made a good Ring bearer himself.

Unless Tolkien addressed this in one of his letters (I really wouldn't be surprised), we don't know for sure, but my guess would be that Sam's resistance was mostly temporary. He could carry it for a short while without succumbing, and he could be around frodo for the whole journey with no issue, but he'd have eventually succumb to it.

Also worth noting that it's heavily implied that the whole thing was predestined by Eru, and so with that in mind, it makes perfect sense that Frodo carries it instead of Sam, because

A) if Sam carried it, it's unlikely he would have trusted Gollem, and his "help" was required in several ways to get the job done

B) Frodo being the carrier + Sam as his sole ally, while not intended by the council of Elrond, turned out to be a formidable match, thanks to Sam's resistance to the ring and his loyalty to Frodo. Idk if when push came to shove, Frodo would have been quite as loyal to Sam as Sam was to Frodo (not with the ring doing it's thing afterall.

Its also worth noting that Tolkien had some kinda weird views about the whole "servant & landed gentry" dynamics, as can be seen in just about every dialogue between Sam and Frodo lol - Sam being the effective leader, despite being a humble gardener and Frodo being basically a Lord in hobbit terms isn't something Tolkien was likely to write

Not entirely. Sam was tempted, and if he possessed the ring long enough he would have been overcome like any other, but his Hobbit-sense saved him in that one small moment:

""As he stood there, even though the Ring was not on him but hanging by its chain about his neck, he felt himself enlarged, as if he were robed in a huge distorted shadow of himself, and vast and ominous threat halted upon the walls of Mordor..."

"Wild fantasies arose in his mind; and he saw Samwise the Strong, Hero of the Age, striding with a flaming sword across the darkened land, and armies flocking to his call as he marched to the overthrow of Barad-dur... He had only to put on the Ring and claim it for his own, and all this could be. "

"In that hour of trial it was the love of his master that helped most to hold him firm; but also deep down in him lived still unconquered his plain hobbit-sense: he knew in the core of his heart that he was not large enough to bear such a burden, even if such visions were not a mere cheat to betray him. The one small garden of a free gardener was all his need and due, not a garden swollen to a realm; his own hands to use, not the hands of others to command. "

In the book, when he was carrying it temporarily for Frodo, the Ring did tempt him. He saw himself at the head of a vast garden, a garden rivaling nations, one that would be free of society and allowed to grow endlessly. The feelings of conquest were justified immediately by the retaking of nature.

Not too bad of a temptation, I dare say.

Ok, I'll bite: WOMEN ALSO HAVE HAIR THERE.

Eh, he had his moments.

He saved the party in the burrow, endured the Nazgul blade in his shoulder, decided to take the burden alone when it started to affect the fellowship, tamed Gollum and got them through Emyn Muil and the Marshes, convinced Faramir to let them go on and keep their guide.

Granted, after being stung by Shelob it was Sam that kept them going, but in the end Frodo even predicted (or maybe more than predicted?) Gollums demise on the slopes of Mt. Doom: "If you touch me ever again, you shall be cast yourself into the Fire of Doom."

For me this is kind of the point of his whole character: He isn't particularly strong or mighty, but he keeps going and eventually fulfills his impossible quest through courage, wisdom and restraint. He most likely wouldn't have come far on his own, but without him there was no hope at all.

Frodo was responsible for being the vessel to absorb and shield the ring's power from others while carrying it to Mt Doom. If Sam himself carried it, he would have eventually succumbed to the ring just like Frodo. No one could really do much alongside that burden.
