While Frozen is great and deserves its place among Disney's classics, The Lion King wins by a mile for me. None of TLK's songs felt lacking, I prefer TLK's more colorful animation, TLK has a background score that I love enough to seek it out to listen to, which is rare for me, and TLK didn't feel like it was lacking in the story department. Frozen was weirdly front-loaded in terms of songs, "In Summer" and "Fixer-Upper" felt pointless, and the magic trolls were awkardly unexplained. I'd still call Frozen great, I just feel like it has a few glaring flaws where TLK doesn't. Frozen being a far more recent film is also knock against it in my book, though that's not Frozen's fault or anything. It's just I've spent 22/26 years of my life obsessed with TLK, and obviously haven't had the same connection with Frozen.
