Ahhh, I've only ever read one SF series that left me with the same sense of wonder as the Lord of the Rings. You just have to try Hyperion/Fall of Hyperion, by Dan Simmons. At first I thought it was ridiculous space opera, with loads of jargon and technical impossibilities that just made it read like 3rd-rate SF. That is right up until the point where Simmons blindsighted me by making all of that stuff an absolutely necessary part of the story. I can be more explicit without giving out a few spoilers, but I've read a lot of SF, and this is really a cut above the rest.
