I'll prefix my question with: please don't post "spoilers".
Before I look at algorithms for solving 4x4x4, I wanted to try solving it on my own. I knew how to solve 3x3x3 with the beginners method, and using that I was able to solve a 2x2x2 unassisted, which wasn't too difficult. Now I know how to solve 3x3x3 with 4LLL CFOP, and I'm trying to get the 4x4x4 solved.
I was able to get all the centers solved, and all the edges paired (that was trickier), and I figured I was done, since I'd essentially turned the 4x4 into a 3x3. However at the end, I've got a couple "impossible" situations for a 3x3, which I understand has something to do with "parity"?? The closest I got was one pair of yellow edges flipped (what would be one edge on a 3x3, therefore unsolvable).
My question is, I'm wondering if it's reasonable to figure out how to fix these cases intuitively, or if the algorithms are too complicated to have any chance without weeks of trial and error.
