Calculus is such a beautiful field with geometrical explanations for almost every theorem. It is the least abstract or dry subject in math.
What is your favourite textbook that made you understand and love calculus (single and multivariable)?

The idea of successive approximations for a slope culminating in a dy/dx term -- where we say dx (really the denominator of the limit definition) is obviously not zero, but is also smaller than any given real number. It's not clear that numbers should work like that.
Pile on that calculus courses (at least in the US) tend to care more about deriving interesting trigonometric/exponential/polynomial/whatever derivatives once using the limit definition and proceed to have students essentially memorize the derivation tricks for the remaining 90% of the course, and it can easily end up being overwhelming.

There's nothing specifically hard about it. Maybe harder-ish than other subjects, but nothing specifically hard (I mean, specifically about Calculus 101 - later ones are of course harder)

But yes, yes and yes. All of that. And wasting too much time with crap like "theorems about limits" which literally nobody cares unless you're on a pure math track.
