I'm watching this show and enjoying it. I'm one of those people that went to the theater to watch the Lord of the Ring movies but really didn't get into them. Forgot the names of nearly every character as I exited the theater. I thought the movies were well done but nothing special. It made it tougher for me because I didn't want to spend the energy memorizing every detail to enjoy the show(s) even more.
With that said, I actually like the streaming shows much better. I can watch them at my own pace and if I happen to miss something, I can rewatch that part. I prefer all the storylines going on at once because they differentiate the groups so obviously. Much like GoT having all those locations and tying them together so well.
You could go the route of my wife and give them nicknames.
Aragorn was "Scruffy Hot Boy" and Boromir was "Scruffy Not As Hot Boy".
21 years later, that's still what they're called.
