Well, tides on moons (eg around gassy supergiants :)) are fairly usual.
So perhaps it’s not as much as the tides being “sci-fi” (sci??) but the relative size of Earth’s Moon (it’s basically a binary planet situation where they orbit around each other).
So, the sheer size of our moon as seen from the planet’s surface is the rarity.
(Then again, on a moon around a supergiant the same experience could be had from one tiny beings pov.)
Ugh, there you go talking smack about my mamma again! Dammit, Evil Shrubbery!
Dense at the core, but what escapes is free for all the solar system to enjoy.
